Phase-coupled two-dimensional AlxGa1−xAs-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.
