Low-cost high-performance wavelength-division-multiplexing (WDM) monitors and receivers are key components in WDM transmission and local area optical networks. A semiconductor arrayed waveguide grating integrated with a photodiode is attractive because of its small size and simple fabrication process. A low-loss (7.3 dB) polarization-insensitive packaged WDM monitor has been fabricated in an industry-standard butterfly-type module. The eight-channel monitors, which have 200-GHz channel spacing… CONTINUE READING
