We developed efficient external-cavity lasers using semiconductor optical amplifiers and silicon photonics. These un-cooled devices achieve high power efficiency, ideal for hybrid WDM transmitters.

Area of Science:

  • Optoelectronics
  • Semiconductor Lasers
  • Silicon Photonics

Background:

  • External-cavity lasers are crucial for wavelength-tunable and stable light sources.
  • Integrating III-V semiconductors with Silicon-on-Insulator (SOI) platforms offers a path to advanced photonic integrated circuits.

Purpose of the Study:

  • To design and characterize novel external-cavity lasers.
  • To leverage a reflective semiconductor optical amplifier (SOA) with spot-size converters for efficient coupling to SOI waveguides.
  • To integrate Bragg grating mirrors within SOI waveguides for laser cavity formation.

Main Methods:

  • Fabrication of external-cavity lasers using III-V reflective-SOA and SOI waveguides.
  • Edge-coupling of the SOA to SOI waveguides containing Bragg gratings.
