Abstract:
1. A multi-channel optical or optoelectronic device, comprising: a demultiplexer configured to (i) receive a multi-channel optical signal having each of a plurality of wavelengths or wavelength bands and (i) separate the multi-channel optical signal into individual optical signals, each individual optical signal having a unique wavelength or wavelength band; a plurality of detectors on or affixed to a detector mounting substrate, wherein each detector is configured to detect light having one of the unique wavelengths or wavelength bands, each unique wavelength or wavelength band of the plurality of wavelengths or wavelength bands corresponding to a channel of the multi-channel optical or optoelectronic device; and a corresponding plurality of lenses on or affixed to an interior surface of the multi-channel optical or optoelectronic device, each of the plurality of lenses configured to focus light of the unique wavelength or wavelength band towards a corresponding one of the detectors, wherein each detector has a location aligned with an actual focal point of the light having the unique wavelength or wavelength band focused by a corresponding one of the lenses.
