Latest Patents

Atsuo Kozen holds a patent for a semiconductor photodetector. This device includes a photoabsorption layer, an n-type first semiconductor layer, and a p-type second semiconductor layer. The photoabsorption layer consists of an n-type first layer and a p-type second layer that are formed in contact with each other. The first semiconductor layer is positioned on the side of the first layer and features a shorter wavelength at the light absorption edge, along with a lower refractive index compared to the photoabsorption layer. Similarly, the second semiconductor layer is arranged on the side of the second layer, also exhibiting a shorter wavelength at the light absorption edge and a lower refractive index than the photoabsorption layer. When a predetermined reverse bias voltage is applied between the first and second semiconductor layers, the first layer becomes entirely depleted while the second layer is partially depleted. This innovative design enhances the performance of semiconductor photodetectors.
