Narrow perpendicular divergence angle QW lasers

Abstract

Single QW heterostructure lasers are characterized by high quantum efficiency, low threshold current, high output power, and quantum size effect wavelength selectivity. Thin SQW lasers arc also characterized, however, by relatively small nearfield spot size and large beam divergence in the direction perpendicular to the junction plane. This trait of QW lasers results in relatively large coupling losses for optical fiber systems. We present data for a novel depressed-index cladding (DC) laser structure that provides reduced perpendicular far-field divergence angle with acceptable low threshold current densities for lasers emitting at 850 nm.
