A phase-locked array of InGaAsP lasers has been fabricated for the first time. The array utilized diffraction coupling between 10 adjacent lasers to achieve phase locking. Threshold current as low as 200 mA is obtained for arrays with 250 Fm cavity length. Smooth single-lobe far field patterns with

High power semiconductor laser arrays must be mounted in the epitaxy-side down conΓΏguration for good heat transfer and so require a well-controlled solder. Selection of solder is very important in semiconductor laser arrays and stacks. Usually, the solder consists of two layers. The outer layer prev
