Integrated photonics module and devices using integrated photonics modules
Abstract
An integrated photonics module includes at least one light source and a MEMS
scanner coupled to and held in alignment by an optical frame configured for
mounting to a host system. According to some embodiments, the integrated
photonics module may include a plurality of light sources and a beam combiner
coupled to the optical frame. According to some embodiments, the integrated
photonics module includes a selective fold mirror configured to direct at least
a portion of emitted light toward the MEMS scanner in a normal direction and
pass scanned light through to a field of view. The selective fold mirror may use
beam polarization to select beam passing and reflection. The integrated
photonics module may include a beam rotator such as a quarter-wave plate to
convert the polarization of the emitted light to a different polarization
adapted for passage through the fold mirror. The integrated photonics module may
include one or more light detectors.
