Abstract

Stable single transverse and longitudinal mode cw operation has been demonstrated using a newly developed gaussian channel substrate (GCSP) laser structure. These devices operate in excess of 14mW and are predominately single longitudinal mode over their entire operating range. Highly reliable performance is also expected due to low threshold current (16mA) and very high differential quantum efficiency (52% for single face). Using a tapered polished fiber technique, coupling efficiencies as high as 35% using 3 μm core single mode fiber were attained for cw lasers in the 840nm range. These devices appear ideally suited for use as optical sources for fiber optic interferometric applications.
