Title: Meir Orenstein: Innovator in Laser Technology

Introduction

Meir Orenstein is a notable inventor based in Old Bridge, NJ (US). He has made significant contributions to the field of laser technology, holding 2 patents that showcase his innovative approach to surface-emitting lasers.

Latest Patents

Orenstein's latest patents include a "Phase-locked array of reflectivity-modulated surface-emitting lasers" and a "Planar array of vertical-cavity, surface-emitting lasers." The first patent describes a method of fabricating an array of vertical-cavity, surface-emitting lasers that allows the lasers to be phase-locked. This device features a growth process for a laterally unpatterned epitaxial vertical-cavity structure, which includes a partially reflective upper mirror and a gold layer that supplies the final reflectivity. The design incorporates a grip pattern etched in the gold layer, with a lower reflectivity metal layer deposited over it. This configuration ensures that the grid portion does not lase while allowing the closely separated areas within the grid to lase coherently. The second patent outlines a planar array of vertical-cavity, surface-emitting diode lasers, detailing a method of making the device. It consists of an active region with a quantum well region situated between two Bragg reflector mirrors, which are separated by the wavelength of the emitting laser.
