Hi. What are the subfields of photonics (applied or fundamental), which are currently the subject of active academic research? I have long been inclined towards optical fiber sensing, toyed a little with the idea of researching multiplexing techniques. However, the more I read research papers, the more I feel that there is no gap left. Quite frustrating! Semiconductor photonics seems to be an interesting research subfield, but I cannot come up with any original research ideas. Please, if anyone could point me in a good direction, I would very much appreciate it. Thanks

I am sure you have consulted Google. If you cant find something good there, I doubt you will find on this Nairaland.

You are not ready! PhD research topic is a love affair.... you can't be pushed into it...nah! It must start from deep within you... For it to be meaningful.

He needs to discover why he's doing the PhD in the first place
What he plans to do with the degree .... It's not just about getting a certificate
