Abstract

We demonstrate a distributed Bragg reflector strained-layer multiple-quantum-well laser at 1.5 μm wavelength with an integrated tapered waveguide beam expander. The far-field’s in the lateral and vertical directions are 10 and 15°, respectively. A quantum efficiency of 17% out the tapered facet was measured with a corresponding threshold current of 28 mA. The alignment tolerances for coupling into a cleaved single-mode fiber are 9.5 and 7.5 μm FWHM in the lateral and vertical directions, respectively. We obtained a 3-dB improvement for single-mode fiber coupling using a SELFOC lens.
