Latest Patents
One of his latest inventions is the hole-injection type separate absorption and multiplication avalanche photodiode (SAMAPD). This innovative device separates the absorption layer and the avalanche layer from a conventional avalanche photodiode (APD). By doing so, it allows a majority of the voltage bias to be applied across the avalanche layer, which is made of high energy bandgap material, thereby enhancing the avalanche multiplication effect and increasing optical gains. The design also minimizes the voltage bias across the absorption layer, effectively reducing dark current. Utilizing i-a-Si:H material for the avalanche layer and i-a-Si.sub.1-x :Ge.sub.x :H material for the absorption layer, the SAMAPD achieves an impressive gain of 686 at a reverse bias of 16V under an incident light power of P.sub.in =1 μw. This invention is particularly suitable for long-distance optical communication applications.
Another significant patent is the integrated photoreceiver featuring a metal-insulator-semiconductor switch (MISS). This photoreceiver consists of a substrate with the MISS formed on one portion and a photoreceiving structure on another portion. The photoreceiving structure captures light signals and generates current signals to trigger the MISS in response to the incoming light.
