[[Optical Component]] Aligning and directly optically coupling photodetectors to optical demultiplexer outputs in a multichannel receiver optical subassembly

A multi-channel receiver optical subassembly (ROSA) such as an arrayed waveguide grating (AWG), with outputs directly optically coupled to respective photodetectors such as photodiodes. In one embodiment, an AWG may be configured such that optical components of the AWG do not interfere with direct optical coupling, and the wire bonding points...
