【 摘 要 】

Optical design of multilayer filter has been carried out using a particle swarm optimizer algorithm. The filters are designed to work for wavelength in the range of 1550 - 1600 nm. Our calculation results show good convergence rate and higher performance in comparison with results based on genetic algorithm. The calculated result for band pass filter layers of Sio2and SnTe have also shown that the transmittance parameter is about 0.994. The results for narrow filters show that the values ofSandPreflectance parameter are in fair agreement with other methods and average transmittance parameter is about 0.985 which is 25% better than flip-flop results.
