DEVELOPMENT OF A PHOTONIC INTEGRATED TRANSCEIVER CHIP FOR WDM TRANSMISSION

With the observed expansion of fiber-optic networks and the movement o f line terminals towards the individual customer the need for cost-eff ective fabrication of customer access modules for interactive services arises. Monolithic integration of the module functions on InP is freq uently seen as a means to reduce module costs. Here we describe a gene ric fabrication process for InP photonic integrated circuits and demon strate an initial transceiver chip with transmit, receive and 1300/153 0 nm wavelength division multiplexing functions. The chip output power reaches 1 mW at 1530 nm with a laser threshold current of 20 mA. The detection efficiency at 1300 nm is 0.1 A/W of fiber power.
