Abstract

Integrated superluminescent diode (SLD) was fabricated using an AlGaAs semiconductor quantum well (SQW) heterostructure wafer. A 3 μm-wide SLD with 300 to approximately 500 μm length is aligned with the 3 μm-wide input aperture of the tapered amplifier. The amplifier is 1.3 to approximately 1.5 mm in length and the gain region expands linearly from 3 μm-wide at the input end to 110 to approximately 130 μm at the output end. The outside stripes of SLD and amplifier regions were etched slightly for restricting lateral current diffusion. Light-current (L-I) characteristics of the integrated SLD were measured under pulse conditions.
