Abstract
An integrated wavelength division multiplexing (WDM) optical transceiver comprises the following elements: (1) a light source; (2) an array of photodiodes responsive to a plurality of optical signals and forming a plurality of electrical received information signals therefrom; and (3) a photonics integrated module (PIM) including transmission components and receiving components necessary to provide transceiver functionality. The transmission components include a demultiplexer, an electro-optic modulator array, and a multiplexer for combining a plurality of modulated optical signals onto a single output signal path as the transceiver output. The receiving components include a demultiplexer responsive to an incoming WDM signal for separating each wavelength component and creating a plurality of received optical signals.
