Abstract :
A Wavelength Division De-multiplexer has been proposed based on a hexagonal lattice 2D photonic crystal structure. The structure has been designed using GaAs rods, dielectric constant 11.4, which are suspended in air. The device has been proposed for De-multiplexing two wavelengths of 1.31 μm and 1.55 μm. The Plane Wave Expansion method and the Finite Difference Time Domain method have been utilized for simulating the photonic band-gap and results respectively. The localization property of photonic crystal has been exploited to guide the wavelengths in two different output paths thereby obtaining low crosstalk and more than 70% of transmission.
