Abstract

In this paper, an all optical 4–2 encoder based on triangular lattice Photonic Crystal structure is proposed. The proposed structure consists of three micro-cavity resonators placed next to each other, resonates at the operating wavelength of 1550 nm to perform the encoder logical operation. The normalized output power for ON state is above 28%, and OFF state is below 0.9%. The minimum time delay and the bit rate of the proposed encoder are about 800 fs and 1.25 Tb/s, respectively. The total footprint of the proposed encoder is around 125 µm2.
