Abstract
Designs of optical devices providing multiplexing or demultiplexing functions are disclosed. According to one embodiment, an optical device or an assembly employs an array of micro lenses, an array of filters and a mirror or an array of mirrors all bonded onto a substrate to provide multiplexing or demultiplexing functions. To compensate for possible errors caused by some or all of these components, one or more compensatory optical plates are provided to respectively correct these errors. Depending on implementation, the compensatory optical plates may be designed differently to correct various errors.
