1. Optical engineering undergraduate knowledge is too diverse. Not only optical physics, there are electrical aspects, but also to learn computer algorithms, each learning a little bit and not in-depth as no learning, out of employment is difficult to meet the needs of enterprises.
2. Then the graduate stage. Optical engineering research to do things does not mean that optics, pure optics, optical engineering in addition to active optics, optical design and so on a few directions, all of which are electrical and computer! There are even mechanical ones ....... If you want to do pure optics, please turn left and enroll in the optics program, of course there are quite a few people in the optics program who don't do optics .... Pure optics in addition to optical design, basically can only read the blog into the Institute and the University, and optical design no one to bring simply can not get into the door, do not expect a big boss, a month may not be able to meet a few times, choose the optical design before you must ask to find out if there is no optical design of the senior brother! But I have to say, optical design is very suitable for lazy people, knowledge is basically fixed, do not need to update often, it is important to accumulate experience.
Next, talk about the computer and electrical aspects of the computer, mainly image processing, which has algorithms also have a combination of hardware, such as fpga, dsp, gpu. However, do not recommend to engage in the algorithm, graduate students really learn something on a year, engaged in algorithms, dry but computer specialties, or with the point of the hardware to mix a meal it. The image processing positions recruited are required to deep learning and machine learning, to do machine vision system will require C++, opencv, circuitry, motion control boards, typical of those who can do more work but not more.
I hope my answer can help you.
I don't know where you quoted the "discouragement of majors" from, whether it means that this major shouldn't exist or it's not recommended.
In addition, the application of the mentioned wide, it depends on and what specialties than, if and e-commerce, condensed matter physics, biomedical and other comparisons is really quite wide, but and electronic, mechanical, computer than completely not counted wide.
Optical engineering major employment direction and enterprises:

Recommended colleges and universities (Huaxu, ZJTU, TianDa, SZD, SUST, ChangTechnic, Xidian, Harbin University of Technology, Shanghai Jiaotong, etc.)
In short, the application of optics there is still a lot of potential, that is to say, the whole industry is not very large, but there are still uncharted territories that can be developed, because the study of light is not very mature, even though it is an electromagnetic wave can be fully explained by Maxwell's equations like other electronic devices, but light is still a particle or a boson.
Also, optical stuff is real economy and is not destined to be as profitable as computers and finance.
The last is that the future development of high precision mean are based on mechanical, electronic, computer and optical, such as lithography. Mechanical, electronic or computer products alone cannot last forever. For example, Internet technology has to have machines as a basis.
This specialty is engineering with light. In the former Soviet Union, corresponding to the "optical precision machinery", in the United States is a small branch of electrical engineering, but there is no "optical engineering". In fact, "optical information science and technology", is some of China's scientific research to do military projects, professors, researchers to the central government to write a letter of advice, jointly proposed, there is no basis for private enterprise. And private enterprises, is the largest market to digest the talent. Therefore, this professional construction is more or less the flavor of the command economy. In fact, you can also be understood as the research direction of the various subject groups
In the global distribution is extremely uneven, basically only distributed in a few highly developed capitalist countries.
Optics this piece of industry on the roughly divided into 1. lens design, microscopy technology; 2. interferometry; 3. optical communications and silicon photonics; 4. solar energy
4 is materials science.
3. If you can search the Internet yourself.
1 and 2 are the two biggest industries. Germany and Japan are stronger than 1, such as Zeiss, Canon, Nikon, the United States is stronger than 2, in fact, from China's CAEP, the United States to see LLNL know that the 2 direction is actually a quasi-military industry (a small part of the standardized metrology, the China National Institute of Testing and Technology is engaged in the metrology, academician Gao Jie is the honorary president). So many Chinese students studying optics get a U.S. degree, but can not enter the U.S. optical industry (no green card without clea; no clea no work and no green card), because the U.S. defense military spending is too large, 2 this direction in the U.S. is very absorbent, many U.S. private enterprises are fishing for oil and water in this area, but the interference and other technologies are very easy to run into the military aerospace. So a lot of Chinese people in the United States to read optics, if you do not take the faculty, either to do civilian optical design or turn image processing or simply computer.
1 words whether to go to Japan or Germany, around the two foreign
Some people take "XX Beijing to engage in the optical design, after jumping ship how many thousands of dollars a year" to say things, in fact, of course, how many thousands of dollars and engage in the light of the design of the relationship between the small, but rather, it is more able to illustrate that the domestic industry is small.
Big research and small production research and industry disconnect, because the private optical industry is weak.
In Germany, the selection of w3 or c4 professors must have industrial experience. That is, to have a period of work experience in the position of the industrial sector of industry, but unfortunately, not in our country.
Some professors suggest that Germany is not good, go to the US ...... In these days of faculty saturation, is the road to getting a faculty job wide or the road to industry wide? This suggestion is exactly the opposite
Shouldn't the ranking of university engineering include the country and regional industry? What's the point of just having a lot of papers? What is the academic significance of doing some second- or third-rate optical work and submitting it to a materials journal and winning it. Thesis is more, it is difficult to recruit excellent students; even if the training, the students will have to change their specialties after graduation, so how much contribution to the discipline? It is a waste of teaching and research resources! If students insist on specialization, then run to the developed countries.
So I think, if you are a boy, think you will go on the road of scientific research, that optical engineering is good. If you are a girl, in addition to the same as boys, if you want to go to the doctorate to find a college to have a second child, it seems to be okay. Of course, if you think the outbreak will upset the shuffle, then you can try that too.
Alas, the keyboard warriors are too lazy to comment or don't know where to start spewing [muffled]. You can imagine how cold. However, it is recommended that this discipline should be directed to training into the research institute, marketization can not get basic science.
Discouragement of professional none of the employment is worrying, there is a prospect of wide employment does not mean that the pay is high, undergraduates are cabbage, employment prospects are for graduate students talent.
Optical engineering is divided into two categories, one from the horizontal point of view, optical engineering can choose the Institute of good companies are relatively few, the employment surface to be narrower, compared to the mechanical, electronic and other specialties are far less good employment. From the vertical point of view, the employment surface of the above types of specialties, relatively speaking, are about the same, the employment prospects as well as the employment surface are relatively good.
Optical engineering students after graduation are mainly engaged in optical design and optical instrument design, manufacturing and maintenance, the average salary of about 2500-6000 / month. It is not difficult to understand that optics has become a persuasive profession.
Because we then how the child can not make photolithography
Nima, now hard engineering majors, optical and electrical, have become a dissuasive profession. How can this be a manufacturing powerhouse? Don't listen to a bunch of laymen blind worship, there is no bad profession, only not progressive people. My brother's bachelor's degree is mechatronics, doctoral studies optical instrumentation.
High school classmates are long optical machine graduates, graduated to the unit shipyard found the most suitable position is the quality of _ optical measurement. Now it is the second largest shipyard in China's quality to pay the manager.
Optical engineering each school focuses on different, employment surface is not very narrow, is very wide! It is a very wide range of disciplines. Need to master the knowledge of optical mechanical and electrical calculations, if partial physics and materials employment may not be very good, if partial computer and communications, employment is still quite good. That said, which specialty does not engage in materials? Even communications engineering! So this specialty is very mixed, the key depends on your direction, and your ability!
