Optically-Pumped Semiconductor Waveguide Amplifier

Technology #11538

Key Points

  • A power semiconductor waveguide optical amplifier (P-SWA)
  • Offers flexibility in the number of quantum wells (QWs), solving the fundamental issue between power and noise figure
  • Applications include photonic integrated circuits, telecommunications


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.
