WDM transmitter or receiver including an array waveguide grating and active optical elements

摘要

An optical component is formed on a silicon on insulator (SOI) substrate and has an array waveguide that demultiplexes an input light signal into N channels and provides that light signal to a corresponding set of N waveguide structures formed on a surface of the SOI substrate. The N waveguide structures provide the N channels of light to N optical detectors. Each optical detector is bonded to a surface of a corresponding one of the waveguide structures. The N channels of light pass through the N waveguide structures and are coupled into the N optical detectors so that light from a corresponding channel of the array waveguide is coupled into a corresponding optical detector and converted into an electrical signal.
