Vertical laser emitter and manufacturing method thereof Interuniversitair Micro-Electronica Centrum vzw
According to an aspect of the present inventive concept there is provided a light emitting unit, for emitting laser light at a laser wavelength, arranged on a planar surface of a substrate. The unit comprises a first reflective element to reflect light at the laser wavelength, a gain element to amplify the light, and a second reflective element to partially reflect the light, and to emit the laser light. The elements form a stack of layers integrated onto the planar surface. Each layer is parallel with the planar surface, and the gain element is arranged between the first and second ...
