Paper Abstract

Edge-emitting laser diodes operating at 900 nm are designed and fabricated with an epitaxial one-dimensional photonic crystal (PC). PC structure consists of a p-waveguide layer, an active quantum region, and an n-waveguide layer. The p-cladding totally reflects one tilted optical mode. The PC with a particular band structure confines the optical mode with a certain tilted angle. Meanwhile mode extends vertically due to the photonic band modulation at the direction perpendicular to the interface. Then we obtain the broad-area lasers with a narrow vertical far-field divergence of 10°, and a small thermal shift (dλ/dT~-0.06 nm/K) in continuous wave operation.
