DIODE LASERS TYPE OF DEVICES WITH GOOD COUPLING BETWEEN FIELD DISTRIBUTION AND GAIN

摘要

Diode laser array type of devices with a periodic arrangement of active element segments and passive inter-element segments. The segments have equal effective refractive indices so that the active elements are coupled and operate on one or more supermode. The array is arranged between lateral boundary segments having a lower effective refractive index which serves to discriminate the anti-phase supermode against all other modes.
