Abstract
We report on a 1.55-mu m laser diode with an integrated spot-size conv erter fabricated in a single epitaxial step using conventional photoli thography. The laser structure uses a conventional ridge guide for the active layers and a second larger ridge for the passive waveguide. Lo w-beam divergence of typically 9 degrees x 9 degrees results in about 3-dB coupling losses with a cleaved optical fiber.
