ABSTRACT: A very compact (80 - 100 μm2)
integrated power splitting devices with two outputs (1 × 2), four
outputs (1 × 4) and six outputs (1 × 6) channel has been designed, simulated and
optimized for Telecommunication purpose with T-Junction, Y-Junction, PC line
defect waveguides integrated with multimode interference block (PCLD-MMI) and
multiple line defect PC waveguides (MLDPCW) configurations. The optical
modeling of these proposed structures was investigated by finite difference
time domain (FDTD) simulation. With the optimization of the parameters (Hole
Radius, R = 0.128 μm, Input
Diameter, D = 1.02 μm,
Input wavelength, λ = 1.55 μm,
Substrate Reflective Index, nsub = Si(1.52), Photonic Crystal Material, npcs = InAs(3.45), and Rectangular crystal structure), 1 × 2 for
Y-Junction (100%), 1 × 4 for T-Junction (92.8%) and 1 × 6 configuration for MLDPCW (81%) show maximum power transmission.
