Thermally controlled AWG
NEL is the pioneer and market leader of AWG. NEL's AWG combines and splits optical signals of different wavelengths for use in WDM systems. The heart of the device, the AWG, consists of a number of arrayed channel waveguides that act together like a diffraction grating in a spectrometer.
