Abstract

A new optical channel drop filter was proposed based on two-dimensional (2-D) 45ophotonic crystal ring resonators. Its spectral information including intensity, dropped efficiency and quality factor affected by different physical parameters were numerically analyzed with 2-D finite-difference time-domain technique. Near 100% dropped efficiency can be achieved at 1550-nm channel.
