The spacing between the stripes is small (5\u03BCm from centre to centre) and the spacing region is either etched or ion-implanted for better current isolation. The implanted laser oscillates in the fundamental mode. The output beam of this laser can be scanned over a radiation angle range of 7\u00B0 almost linearly with injection currents. The etched laser oscillates in the first-order mode. The output beam of this laser can be switched with a deflection angle as large as \u00B18\u00B0."@en . . . . . . . . . .
