文摘

In this paper a 4×2 optical encoder is proposed by employing the self-collimation effect in 2D photonic crystals. The total structure of the proposed device is a combination of so called “beam splitters” and “mirrors”. The simulation result indicates that, this design can operate as 4×2 optical encoder, the footprint of structure is about 69 µm×55 µm and response time is about 1.4 ps.
