TLDR
A device for optical switches and logic gates is proposed in two-dimensional photonic crystals based on self-collimated beams that resembles that of the plane waves propagated in a homogeneous medium.Abstract:
A device for optical switches and logic gates is proposed in two-dimensional photonic crystals based on self-collimated beams. The main structure of the device is a line-defect-induced 3 dB splitter. Operating principle, as revealed by both theoretical calculation and finite-difference time-domain simulation, is based on the interference of reflected and transmitted self-collimated beams. This device is potentially applicable for photonic integrated circuits.read more
