Compact, wide bandwidth, multi-channel power dividers based on one-dimensional photonic crystal waveguides

We propose novel compact multiport power dividers based on one-dimensional photonic crystal omnidirectional reflective waveguides. The proposed power dividers have advantages of wide bandwidth, flexible extended output channel number and compact size. The power dividers are numerical simulations using finite-difference time-domain method. Near-complete transmission and uniform at every branch of output power of multi-port power dividers are observed within wide frequency range. For a 1D PhC 1 x 6 power divider, the six output port achieved nearly 16.5% transmission at each arm from 1545 nm to 1553 nm and the size of 1 x 6 power divider is 14.3 mu m x 14.3 mu m at 1.55 mu m operation wavelength.
