Phase-coupled two-dimensional Al<i>x</i>Ga1−<i>x</i>As-GaAs vertical-cavity surface-emitting laser array

Abstract

Data are presented demonstrating the optically coupled operation of a 3×3 two-dimensional array of AlxGa1−xAs-GaAs vertical-cavity surface-emitting lasers. Room-temperature threshold current for the array is 90 mA, with the device geometry allowing for light emission from the epitaxial side of the device.
