Abstract
A multi-layer high reflective dielectric optical coating deposited on a laser diode facet that shifts the high amplitude peak of the electric field associated with the reflection of light away from the interface between the semiconductor material and the reflective coating, and into the reflective coating itself. By shifting the electric field peak in this manner, the laser diode can operate at much higher optical output powers without inducing catastrophic optical damage at the non-output facet.
