Abstract :
The 3D FDTD method is used to obtain loss versus hole depth in a 2D photonic crystal waveguide by simulating two different length guides. The transmission results are validated against published measured data. Good agreement between measured and simulated data is obtained for a mini-stop band of the PC WG. Intrinsic loss has been extracted from different length guides and an estimate of the lower bound of waveguide loss has been made.
