Abstract

The light output of an injection laser is of higher intensity in certain selected portions of an active region adjacent the junction. These portions vary with the current.

Solid State Laser Pattern Control

The light output of an injection laser is of higher intensity in certain selected portions of an active region adjacent the junction. These portions vary with the current.

Control of the light output can be accomplished by selectively applying a dielectric film over the surface. The film can be used to provide a uniform light output at a higher threshold current by masking the low threshold portions. Patterns of the dielectric film can be used to perform logic.
