Latest Patents
Kyung-ho Ha holds a patent for the "Assembly of VCSEL light source and VCSEL optical detector." This invention provides an assembly that integrates a light source and an optical detector, both utilizing VCSEL technology. The design allows for the control of light emission from the VCSEL light source by converting spontaneous light emitted laterally into an electrical signal. The optical detector is strategically placed around the light source to supply feedback through this electrical signal. The unique circular inner surface of the optical detector absorbs spontaneous light, while its polygonal outer surface, featuring peaks and valleys, enhances the reflection of light within the detector. This design effectively increases the intensity of light converted into an electrical signal.
