Abstract
In this letter, the authors report the first demonstration of laser operation in long-wavelength optically-pumped vertical-cavity surface-emitting lasers for photonics-on-complementary metal-oxide-semiconductor back-end integration using 1-D double photonic crystal mirrors. The full exploitation of surface-addressable slow Bloch modes in such photonic architectures promotes an optimized tailoring of light confinement resulting in compact single-mode emitters capable to operate continuous-wave with thresholds in the sub-mW range.
