Which units are suitable for those who study optics and have a postgraduate degree?

First of all, let me explain that there are not many well-established and famous schools in traditional optical engineering disciplines, unlike other mechanical and electronic schools. I graduated from Zhejiang University in optical engineering. Let me tell you about it. Employment situation, if you are from a general school, you can have a reference. I graduated with a master's degree in optical engineering and currently work in a certain research institute. According to what I know and what my friends have learned, 70% of undergraduates who have graduated from optics have basically changed careers. Just go to Huawei or other non-professional companies, and some even change careers after working in the optical field for one or two years, and go to work in electricity, communications, microcontrollers, etc. The employment of students studying for a master's degree is basically the same as that during the master's degree. The topics we do are closely related, including software, hardware, image processing algorithms, optical design, coating, processing and testing, etc. Basically, those who work in software and hardware, even if they have a master's degree in optical engineering, will naturally change their jobs. Those who work in image processing are my classmates who are doing optical image processing, semi-switching, optical design, coating, processing and inspection. Let’s continue walking along the path of optics. Talking about the companies that are suitable for graduate students, I have to say that the employment opportunities in optical engineering are still very narrow compared to those in machinery and electronics, and they are getting narrower and narrower even after getting a Ph.D. The reason is mainly because the domestic optical field is not developed enough. Most of the people engaged in this field are in research institutes, such as Changchun Institute of Optics and Mechanics, Shanghai Institute of Optics and Mechanics, Chengdu Institute of Optoelectronics, Xi'an Institute of Optics and Mechanics, Shanghai Institute of Technology, and Anhui Institute of Optics and Mechanics. There are only a few research institutes in the country that focus on optics, which are completely equivalent. I work in one of them. Most companies are concentrated in Beijing, Shenzhen, and Shanghai. There are also some optical companies in Hangzhou, Suzhou, Chengdu, Xi'an, and Wuhan, but there are few or none in other cities. But there are a lot of companies in any city in these majors such as mechanics, electronics, and electrical. The key point is that optical companies are basically companies that serve the radio and television industry. There are very few companies that use the advantages of optics to focus on developing their own direction. For example, optical coating companies, optical platform parts manufacturing companies, optoelectronic instrument production companies, LCD panel production companies, etc. In short, there are still very few counterpart companies in comparison. As for employment prospects, horizontally I can only say that there are fewer research institutes and companies to choose from in optical engineering, and the employment opportunities are narrower. In comparison, they are not as good as those in machinery, electronics, etc. But from a vertical point of view, basically all of my master's students are employed, and they all feel pretty good. It's not more difficult to get into optical research institutes and companies than it is in electronics and machinery. From this point of view, it's actually pretty good. Besides, many of my classmates went to Huawei after graduation. Since you asked about companies like Huawei and ZTE, do they match up? To be honest, this kind of unit recruits people based on personal qualities rather than professional background. My friend is purely engaged in theoretical physics. Still go to Huawei. In front of such a quality-testing unit, students majoring in optical engineering, mechanics, electronics, etc. have equal opportunities. Studying optical engineering will not affect your entry into Huawei at all, but what is important is what you can learn during graduate school. What kind of improvement.

Let’s write this much first. If you have any other questions, please leave a message to me. I will try my best to tell you everything I know. I hope it can help you
