Silicon photonics requires enhanced device performance for telecommunications. A new Si-Ge-silica platform enables integrated modulators, detectors, and filters for broadband applications.

Area of Science:

  • Photonics
  • Materials Science
  • Telecommunications Engineering

Background:

  • Silicon photonics (Si photonics) is crucial for telecommunications but requires improved device performance.
  • Current Si photonics devices face limitations in achieving the necessary efficiency and functionality for practical applications.

Approach:

  • Developed a novel monolithic integration platform using silicon-germanium (Si-Ge) and silica.
  • The platform employs low-temperature silica film deposition to protect sensitive Si-Ge active devices.
  • Integrated compact Si-Ge modulators/detectors and high-performance silica-based wavelength filters onto a single platform.

Key Points:

  • Demonstrated monolithic integration of Si-Ge modulators, detectors, and silica wavelength filters.
  • The low-temperature deposition process preserves the integrity of Si-Ge active components.
