VERTICAL-CAVITY SURFACE-EMITTING LASERS WITH NON-PERIODIC GRATINGS |
摘要 |
<p>Various embodiments of the present, invention are directed to surface-emitting lasers with the cavity including at least one single-layer, non-periodic, sub-wavelength grating. In one embodiment, a surface-emitting laser comprises a grating layer (112) configured with a non-periodic, sub-wavelength grating (122), a reflective layer, and a light-emitting layer (102) disposed between the grating layer and the reflector. The non-periodic, sub-wavelength grating is configured with a grating pattern that controls the shape of one or more internal cavity modes, and controls the shape of one or more external transverse modes emitted from the surface-emitting laser.</p> |
