Abstract

The invention is applicable to the technical field of photoelectronics, and provides a photoelectric detector chip, a photoelectric detector chip circuit and a photoelectric detector, the photoelectric detector chip is composed of a preset photoelectric detector chip and a converging lens integrated on the preset photoelectric detector chip, the converging lens is used for converging the incident light signal to a photoelectric conversion photosensitive surface of a preset photoelectric detector chip. Because an incident light signal can be transmitted to the photoelectric conversion photosensitive surface of the preset photoelectric detector chip through a shorter optical path with smaller loss after being converged by the converging lens, more light with the same emergent power can be transmitted to the photoelectric conversion photosensitive surface of the photoelectric detector chip; therefore, the photoelectric conversion efficiency of the photoelectric detector chip is improved. And compared with the mode of coupling the optical lens and the preset photoelectric detector chip by adopting a saddle frame/angle iron and the like, the positioning precision is higher, the coupling difficulty is lower, and the consistency of the device is better.

Description

technical field [0001] The invention belongs to the technical field of optoelectronics, and in particular relates to a photodetector chip, a photodetector chip circuit and a photodetector. Background technique [0002] Microwave photonics is a fast-growing interdisciplinary subject, and it has been widely used in national defense, science and technology, and many aspects of daily life. Among them, the photodetector chip is the key component to realize photoelectric conversion, and is the core device in optical communication, microwave photonic radar and other systems. [0003] When the photodetector chip works, it needs to match the optical system of the signal, that is, the change center of the incident light needs to be within the linear range of the photoelectric characteristics of the photodetector. Because the incident light needs to be irradiated on the photoelectric conversion photosensitive surface of the device for photoelectric conversion, if the incident position...
