I’m studying optoelectronic engineering as an undergraduate in China.

My current plan is to pursue a master’s degree in Europe and, if possible, stay there to work afterward.

I hope to work in semiconductor lithography or advanced semiconductor manufacturing equipment.

I’m particularly interested in the equipment and systems side.

From what I understand, Europe has a relatively strong ecosystem in optics, photonics, precision engineering, semiconductor equipment, and related supply chains.

The Netherlands and Germany seem especially attractive, although I’m also looking at countries such as Belgium and France. And if I’m qualified or lucky enough, Switzerland will also be an option.

The US is probably not a realistic option for me because of the high cost.

I’m hesitant about staying in China long term because the graduate job market is extremely competitive, while compensation and working conditions for many entry-level engineering roles are not particularly attractive.

I’m also wondering whether my current plan might be a bit overly optimistic.

I’d really appreciate any advice or personal experiences from people who are already working in the industry. Thanks a lot!

Open Innovation Concept: Ultra-thin optical band that turns night into daylight (360° vision)

"Hello everyone. I am not a technician or an engineer, and I am not looking for patents or economic rights. I just want to share a conceptual idea and see if optical engineers find it interesting from a technological standpoint.

The Concept:

Imagine an ultra-thin metal band (about 2 cm wide) worn over the eyes, exactly as shown in the attached images. There are no screens, no image projection, and no user interface.

When you put it on at night, the real environment around you (in full 360 degrees, including peripheral vision) looks as bright as midday, with a warm, golden daylight glow (as seen in the bottom image). It is not AR or a display; it is the real world, passively amplified and transformed.

The Technical Challenges:

I know this doesn't exist today. Current night vision requires thick tubes, and smart glasses use cameras and displays. So, my questions for the experts are:

1. Is it possible to achieve this light amplification without screens, using metamaterials or nanolayers on such a thin band?

2. How could ambient light be captured and amplified in 360 degrees without blocking normal vision?

3. Is there any optical material or filter capable of converting faint night light into this warm daylight effect?

The images are AI-generated concept art to illustrate the idea. I would love to read the thoughts of people who understand optics and physics. Thanks!"
