LiNbO 3 Wavelength Router Using Bridged Planar Spectrographs

We propose a wavelength router composed of a pair of connected planar spectrographs to attain multiple input and output ports. The equal-length waveguide array connecting the two planar waveguides is used to relax fabrication tolerance. The crosstalk below -20 dB and filter bandwidth of 5 nm were at...

Summary:We propose a wavelength router composed of a pair of connected planar spectrographs to attain multiple input and output ports. The equal-length waveguide array connecting the two planar waveguides is used to relax fabrication tolerance. The crosstalk below -20 dB and filter bandwidth of 5 nm were attained with a device fabricated in LiNbO 3 .
