Abstract
Laser diodes with a narrow and circular output beam are of great importance because they enable us to get high coupling into single mode fiber with a large alignment tolerance. LDs with mode-field-converter (MFC-LD) to increase the optical spot size are intensively investigated [1]-[4]. Monolithically integrated either vertically or laterally tapered waveguide is usually used for MFC. A simple fabrication of integrated vertically tapered waveguide has been reported utilizing selective area epitaxy of QW structure onto the dielectric patterned substrate [3].
