Abstract

A lateral cavity photonic crystal (PhC) surface-emitting laser is realized on a commercial epitaxial waveguide wafer without a distributed Bragg reflector first. Energy is coupled from the lateral resonance to surface-emitting light through the Γ band edge of the PhC with a square lattice. Electrically driven 1553.8nm surface-emitting lasing action is observed at room temperature. The threshold current density of 667A/cm2 is ultralow for the surface-emitting laser.
