Optical filtering

Our FBG expertise allows us to develop custom narrow passband optical filters. Our passive filters can be used in dense high-speed DWDM systems where high channel isolation is required. Passbands as low as a few tens of MHz have been realized in single-channel or multichannel configurations for RF signal filtering. As for our tunable optical filters, the thermally controlled platform can be designed to scan anywhere in the C band with a bandwidth of less than 10 GHz and an isolation greater than 40 dB.
