Abstract(in English) We developed a laser diode(LD)integrated with a polyimide waveguide on the same GaAs substrate to control(divide or collimate)the emitted light beam To divide the beam from the LD we fabricated a groove to act as a half-mirror in the polyimide waveguide. When the incident angle to the groove surface was a little below the critical angle at a suitable groove width, we obtained the half mirror effect. Additionally, to collimate the beam in the horizontal direction inside the polyimide waveguide we fabricated a parabolic-shaped total internal reflection mirror in the polyimide waveguide. The far field pattern(FFP)was measured to be 1.8°.
