A high-power, single-mode laser structure based on screening of supermodes in vertically coupled waveguides is proposed and demonstrated in the $1.3 \mu \text{m}$ wavelength range. This supermode-screening (SuMoS) laser operates in a single large mode with low ellipticity that is ideal for optical coupling and high optical power at the facet. Fabricated Fabry-Pérot lasers demonstrated low loss ( $\sim $ 1 cm $^{-1}$ ), high power ( $>$ 500 mW), reasonable power conversion efficiency ( $>$ 20%), and good coupling to a lensed optical fiber ( $>$ 80%). |
