Abstract :
In this report, our recent results of an integrated device are reported. The integrated superluminescent diode (SLD) consisting of an LED/laser diode was fabricated using an AlGaAs SQW heterostructure wafer. A 3 μm-wide superluminescent diode with 300-500 μm length is aligned with the 3 μm-wide input aperture of the tapered amplifier. The amplifier is 1.3-1.5 mm in length and the gain region expands linearly
