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

摘要

Diode lasers type of devices with good coupling between field distribution and gain are disclosed. A single element has a flat field distribution that couples with the uniform current injection in a contact region. A multi element array having almost flat field distribution in each element and almost equal amplitude for the field intensity in all elements is provided. Injection by multiple contacts couples well with the overall field distribution. Also, the lasers are stable against filament formation and mode switching.
