Abstract
Consistent with the present disclosure, a compact laser with extended tunability (CLET) is provided that includes multiple segments or sections, at least one of which is curved, bent or non-collinear with other segments, so that the CLET has a compact form factor either as a singular laser or when integrated with other devices. The term CLET, as used herein, refers to any of the laser configurations disclosed herein having mirrors and a bent, angled or curved part, portion or section between such mirrors. If bent, the bent portion is preferably oriented at an angle of at least 30 degrees relative to other portions of the CLET. Alternatively, the curve or bend portion may be distributed over different sections of the CLET over a series of arcs, for example. The waveguide extending between the mirrors is continuous, such that light propagating along the waveguide is not divided or split. The waveguide also constitutes a continuous waveguide path.
