Abstract
In this paper, a dual leaf shaped 4*2 optical encoder is proposed and designed in triangular lattice using Two Dimensional Photonic Crystal (2DPC). The dual leaf shaped ring resonator along with line defects and cavities are introduced in this proposed structure. Plane Wave Expansion method (PWE) is implemented to define the band gap of the proposed structure. The function of the structure is simulated by using 2D Finite Difference Time Domain Method (2D-FDTD). The proposed encoder size is 17.6 μm x 15.2 μm = 267.52 μm2. The proposed encoder is suitable for high speed applications such as integrated circuits and devices.
