    摘要: A disclosed surface-emitting laser element includes a resonator structure having an active layer, a first semiconductor multilayer mirror and a second semiconductor multilayer mirror configured to sandwich the resonator structure having the active layer, an electrode provided around an emission region of a light-emitting surface, and a dielectric film provided in a peripheral portion within the emission region and outside a central portion of the emission region to make a reflectance of the peripheral portion lower than a reflectance of the central portion. In the surface-emitting laser element, an outer shape of a portion where the electrode provided around the emission region of the light-emitting surface is in contact with a contact layer includes corners.

    摘要: A semiconductor light emitting device includes a pump light source, a gain structure, and an out-coupling mirror. The gain structure is comprised of InGaN layers that have resonant excitation absorption at the pump wavelength. Light from the pump light source causes the gain structure to emit light, which is reflected by the out-coupling mirror back to the gain structure. A distributed Bragg reflector causes internal reflection within the gain structure. The out-coupling mirror permits light having sufficient energy to pass therethrough for use external to the device. A frequency doubling structure may be disposed between the gain structure and the out-coupling mirror. Output wavelengths in the deep-UV spectrum may be achieved.
