Ultra-compact, Low-loss and Low-crosstalk Wavelength Demultiplexer for CWDM System Based on the Photonic-Crystal-Like Metamaterial Structure

Not Accessible

Your library or personal account may give you access


A wavelength demultiplexer for CWDM system is designed, fabricated and characterized based on metamaterial structure. The device experimentally displays low loss (−2.3dB), low crosstalk (−16.4dB) and broad 1-dB bandwidth (>18nm) with compact size of 2.6μm×5μm.
