We believe that enhancing the learning experience of students all over the world is a very nice goal. If you agree and ask yourself what you could do to motivate and inspire a lot of people, find out about the several big and small ways to contribute to photonics101.com!

First of all: Thank you to consider contributing to the site! Below you can find the main ways we could think of. Generally, contributors have the option to be referenced on the site, i.e. with name, institution, web link etc. In either case you can contact or via the mail to $$r_\cdot filter\ \alpha\ gmx_\cdot de$$ (please don't copy the mail direcly ;)).

## Share a Post or Background to a specific Problem

In the blog section there is in principle no frontier for your creativity. Please regard the following categories as a proposition what could be done, not as an exclusive list.

## Current Research

Have you written or are aware of a nice publication that can can motivate, explain or simply underline the importance of a certain problem? Please don't hesitate to contact us! We would be glad to include your introductory text and a link to the publication!

### Technical Insight

Maybe you have some technical information why impedance matching in transmission lines is so important? Or you are an expert in Faraday rotators and would like to share some of your insights? Examples like these are often extremely interesting and motivating for students!

### Knowledge Transfer

You are a relativist and have to use some electrodynamics to understand the formation of stars? Please, let us know! A lot of the most ground-breaking ideas in physics and engineering stem from interdisciplinary research. The topics hugely vary and are not only challenging but also stimulating for a general audience.

## Suggest a Problem

We encourage everyone who is motivated to spend some time on an interesting problem and suggest it to us! However, because of limited resources please consider the following guidelines seriously:

• Quality over quantity
• Structure – the problem must at least consist of problem statement, hints and solution.
• Length – Following the hints, what would be the time for a student to find most of the results? The problems should neither be superficial nor extremely involved.
• Format – Please use a plain LaTeX file that runs out-of-the-box with most conventional LaTeX distributions.
• Originality – Of course we cannot re-invent the wheel and a lot of problems will look similar to existing ones. Nevertheless you may not submit problems you simply copied from somewhere like books, lecture notes etc. Also please check if we already have too similar problems on the site.
• Optional
