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.
