Proposal for Compact Optical Triplexer Filter Using 2-D Photonic Crystals

We propose an ultrasmall device size all-optical triplexer based on two-dimensional photonic crystals (PCs). The numerical results show that the proposed PCs' waveguide structure could really function as an optical triplexer with respect to the three wavelengths, i.e., 1310, 1490, and 1550 nm,...

Summary:We propose an ultrasmall device size all-optical triplexer based on two-dimensional photonic crystals (PCs). The numerical results show that the proposed PCs' waveguide structure could really function as an optical triplexer with respect to the three wavelengths, i.e., 1310, 1490, and 1550 nm, respectively. It can be widely used as the fiber access network element for multiplexer-demultiplexer wavelength selective in fiber-to-the-home communication systems. The ultrasmall PC devices are expected to lead to a new class of optical devices, which will take the advantage achieving an optical device of compact build; the total size of the proposed optical triplexer is only 16 mum times 20 mum. The transmission efficiency is larger than 94% and the crosstalk is less than -23 dB.
