TLDR

In this paper, an eight-element phase-locked array of index-guided separate confinement ridge AlGaAs diode lasers is fabricated, and stable radiation patterns of near diffraction-limited single narrow beam with 1.6° width are obtained.

Abstract:

An eight‐element phase‐locked array of index‐guided separate confinement ridge AlGaAs diode lasers is fabricated. In this array the absorption of light in the region between lasers is negligible and the gain profile across the array is nearly uniform. Unlike most other arrays, this array oscillates in its fundamental mode. Stable radiation patterns of near diffraction‐limited single narrow beam with 1.6° width are obtained. The beam width approaches the theoretical limit for the present array structure.

IEEE Journal of Quantum Electronics

TL;DR: In this paper, the authors derived approximate analytical solutions for traveling wave fields within the broad area laser, where the field amplitude consists of a small ripple superimposed on a large dc value, and the matching fields at the boundary determined the modulation depth and imparts an overall phase curvature to the traveling wave mode.

Optical phase conjugation laser diode

Henrichs Joseph Reid

TL;DR: In this article, a phase conjugating array of hexagon apertured hexahedral shaped corner-cube prisms is used to neutralize the phase perturbating contribution of spontaneous emission, acoustic phonons, quantum-noise, gain-saturation, diffraction, and other intracavity aberrations and distortions that typically destabilize any sti mulated-emission made to undergo amplifying oscillation within the invention's phase-conjugating resonator.
