Abstract

Here we compare the performance of InGaAs SQW tapered unstable resonator lasers (TURL) with linear-shaped-taper with lasers that have a trumpet-shaped-taper that follows the shape of the optical mode as it expands while propagating in the laser resonator. The laser resonator is defined by two first-order feedback gratings and is completely separated from the grating outcoupler.
