I have to choose specialisation for my masters degree in applied physics next year. I want to work in the microelectronics industry so the specialisation called "Microelectroncs and Nanoelectronics" seems like a natural choice to study. However I want to know whether another specialisation called "Optics and Photonics" would be more appropriate for working in the microelectronics industry in the long run due to all this talk about the future of the electronics industry relying more heavily on photonic circuits. My question is whether the photonics and optoelectronics industry is mature enough to move from the experimental stage to a large scale commercial stage in the near future to replace microelectronic circuits. If so it would be more beneficial to me to jump straight into the business and do the photonics specialisation instead in order to get an competitive edge?
