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