Abstract
In general, the present disclosure is directed to an optical turning mirror for receiving channel wavelengths along a first optical path and reflecting the same towards a fiber or photodetector (PD) without the necessity of disposing a highly reflective layer to increase reflectivity. In more detail, the optical turning mirror includes a substantially transparent body, e.g., capable of passing at least 80% of incident wavelengths, that defines an input region with integrated focus lens(es) for receiving channel wavelengths along a first optical path and a reflective surface disposed opposite the input region to direct/launch received channel wavelengths along a second optical path towards an output interface having an angled light-transmissive surface, with the second optical path extending substantially transverse relative to the first optical path.
