Abstract

The University of Central Florida invention is a device that incorporates a conventional laser monolithically integrated with a totally undoped semiconductor optical amplifier (SOA) that can produce more than 20dB of optical gain in an overall length of less than 100 μm. A 2-D array of such devices can easily be flip-chip bonded onto a silicon photonic integrated circuit (PIC) for applications such as high power free-space communications.
