In order to solve the problem in the conventional superluminescent diode (SLD), i.e. its output power is not high enough for some applications, a monolithic superluminescent source by integrating SLD with the tapered semiconductor amplifier has been designed and fabricated. An AlGaAs heterostructure wafer, gain guide of oxide stripe and a way of direct coupling were adopted. The experimental results show that the superluminescent output of SLD can be amplified for about 22 dB by the tapered optical amplifier. A maximum output power of 580 mW has been obtained under pulsed condition.
