A 1.3-μm Lens-Integrated Horizontal-Cavity Surface-Emitting Laser with Direct and Highly Efficient Coupling to Optical Fibers

Abstract

A novel 1.3-μm surface-emitting laser integrated with a monolithic InP bulk lens was demonstrated. The laser achieved very narrow far-field angles of around 2° leading to a −2.7 dB direct coupling to a single-mode fiber.
