Improved Manufacturing of Solid State Lasers via Patterning of Photonic Crystals

Tech ID: 22342 / UC Case 2005-144-0

Brief Description

A method of fabricating solid state lasers with embedded structures for improved performance via patterning.

Background

There is a need to improve the performance of horizontal emitting, vertical emitting, beam shaped and distributed feedback lasers.  Traditionally, photonic crystals placed on the surface of the devices have been used to improve performance.

Description

Researchers at UCSB have developed a method of fabricating solid state lasers with embedded structures for improved performance via patterning. The patterned layer(s) may be engineered to act as a mirror, optical confinement layer, grating, wavelength selective element, beam shaping element, etc. for the active layers. The primary advantage of this technology is that it provides for fabrication of all the needed functionality in one lithography step via patterning.

Advantages

  • Improved performance of the laser
  • Improved contact structures and reduced waveguiding loss by contact electrodes
  • Fabrication via one lithography step makes this invention easily manufacturable at low cost

Applications

  • Fiber optic networks
  • Instrumentation lasers
  • Optical spectroscopy
