摘要

我们已经成功地演示了1×4 MMI阵列激光二极管，该二极管锁相，从单模输出波导获得超过400 mW的功率，每面斜率效率为20%。在418 mW时，在FWHM处测得的远场为16.1°，随着驱动电流的增加，远场仍保持单叶状。当使用相同的有源长度时，这是使用单个脊波导的三倍的改进

Multimode interference coupled array laser

We have successfully demonstrated 1×4 MMI array laser diode which is locked in phase achieving power in excess of 400 mW from a single mode output waveguide with slope efficiency of 20 % per facet. Far field measured at FWHM being 16.1° at 418 mW and remained single lobed as the drive current was increased. This is an improvement over using single ridge waveguide by a factor of three when the same active length is used
