Popis:	In this paper all optical ultra compact 4:2 encoder is proposed and designed using two dimensional photonic crystals. The proposed structure has silicon rods of refractive index of 3.4 embedded in air host by creating line defects in hexagonal lattice platform. PWE method is used to determine the photonic band gaps and structure is analyzed using FDTD method. Further, the proposed 4:2 encoder is operated at 1550 nm and it provides a high contrast ratio of 9.25dB and foot print of the structure is 119.34 μm2. Hence it is highly advisable for photonic integrated circuits and optical signal processing.
