Abstract :

We have designed a new type of optical channel drop filter (CDF) based on two dimensionaltriangular lattice photonic crystals. CDF operation is based on coupling to the photonic crystalwaveguide. The proposed structure is optimized to work as a CDF for obtaining the CDFcharacteristics and band structure of the filter the finite difference time domain (FDTD) method andplane wave expansion (PWE) method are used respectively. Dropping efficiency at 1550nm andquality factor (Q) of our proposed structure are 96.36 % and 282.7, respectively. The quantities
