Notes:
Coupling-loss-arrested misaligned semiconductor laser arrays are designed and fabricated by liquid-phase epitaxy. In these devices, the losses in the normal misaligned arrays is collected by a gain-induced positive waveguide, and then the collected light couples with light in the adjacent waveguides evanescently, therefore avoiding the coupling loss and strengthening the coupling. The constructed co-cavity element should have better characteristics with respect to transverse-mode selection. A clean single-lobe far field as narrow as 3° and a relatively low threshold of 130 mA for a seven-element array are obtained.
