Tunable Laser Source with Integrated Optical Modulator

Tech ID: 22049 / UC Case 2000-027-0

Brief Description

A low cost and low complexity tunable laser source and monolithically integrated optical modulator.

Background

Since tuning laser wavelength directly through bias current is slow and results in challenges such as frequency chirp, external optical modulators have been used for high-bandwidth applications. However, external modulators add significant cost and complexity to the assembly, and thus an integrated modulator is preferred.

Description

Researchers at the University of California, Santa Barbara have developed a device including a tunable laser source and a monolithically integrated optical modulator. The laser has a widely tunable wavelength, and the monolithic integration of the optical modulator makes for a low cost and low complexity system. These benefits are attained while maintaining the high bandwidth capability of a system incorporating an external modulator. This technology is applicable to high speed optical communication networks.

Advantages

  • Widely tunable wavelength
  • Capable of high bandwidths
  • Low cost and low complexity due to monolithic integration

Applications

  • Optical Communication Networks
