| 发明名称 | Two-state negative feedback avalanche diode having a control element for determining load state | ||
| 摘要 | A negative feedback avalanche diode for detecting the receipt of a single photon is described. The photodetector comprises a load element having two load states, one characterized by high impedance and the other characterized by low impedance. The load state of the load element is controlled by a control signal generated within the negative feedback avalanche diode itself. | ||

| 主权项 | 1. A negative feedback avalanche detector comprising: a single-photon avalanche diode; a load element having a first load state and a second load state, the first load state being higher impedance than the second load state; and a control element operable for providing a control signal that determines the load state of the load element; wherein the load element and control element collectively define a load for the single-photon avalanche diode, and wherein the load element switches between the first load state and second load state based on a control signal generated within the negative feedback avalanche detector. | ||
