In-phase emission from index-guided laser array up to 400 mW
Abstract
Phased-array lasers with real-refractive-index waveguides have been grown by metalorganic chemical vapor deposition. The index guides are coupled via 'Y'-type coupling regions and the laser array emits with all elements in phase. Powers of over 400 mW are obtained with no indication of a change in the far-field pattern.
