triplexers based on SOI constructed by three similar resonance cavities

Here we reported capable ultra-compact optical triplexer on silicon-on-insulator substrate with resonance cavity for an application of optical communication network. Three cavities are used which can separate three communication wavelengths 1.31, 1.445 and 1.55µm. Proposed triplexer has the very low cross talk of −25 to −50dB.
