Abstract :
A GaInAsP/InP vertical GRIN-lens (VGL), which is suitable for monolithic integration with semiconductor laser diodes (LDs) or semiconductor laser amplifiers (SLAs), was fabricated for the first time. A narrow FWHM of vertical far-field pattern of 6 degree was experimentally obtained with 8 layers of GRIN core region (8 μm thick) and InP cladding layers. An integration of this VGL with a taper waveguide SLA with the output width of 10 μm was also demonstrated.
