Abstract
We propose a wide angle, efficient and low loss 1 x 3 power splitter based on
triangular lattice air holes silicon slab Photonic Crystal (PhC). Desired power
splitting ratio was achieved by altering the structure at the junction area of the power
splitter. Simulation results obtained using 2-D finite difference time domain method
show that for TE polarization incident signal, the power is distributed almost equally
with total normalized transmission of 99.74% and negligible reflection loss at the 1550
nm optical operating wavelength. In addition, the power splitter can operate at 1388 nm
and 1470 nm optical wavelengths.
