Abstract
The method of the invention is intended for manufacturing a laser diode with improved light-emitting characteristics. The method consists of providing certain components of a laser diode such as a wide-aperture lasing medium that has an active emitting layer with a first end and a second end, a DPH-mode reorganizer that contains a core and a plurality of nanogrooves made in the core and arranged in a pattern that accomplishes a given function and locally changes the refractive index of the core. The method further includes the steps of forming a semitransparent mirror on the second end of the active lasing medium and aligning the first end of the active emitting layer with the core of the DPH-mode reorganizer, thus forming a resonator of the laser diode. In the resonator, the light applied from the laser-active medium bounces back and forth between the DPH-mode reorganizer and the partially reflecting mirror, thereby enhancing stimulated emission.
