Abstract

A multi-channel signal superposition device according to the present invention includes a photosensitive component and several electroluminescent components arranged on the sensing surface of the photosensitive component, and the light-emitting surface of the electroluminescent component is connected to the photosensitive component. The sensing surface is stacked or set close to each other; each current signal is converted into an optical signal by each electroluminescent component, and then the optical signal is superimposed and converted by the photosensitive component on the other side of the substrate, and output as a single current signal . Since the single-channel current signal is converted into an optical signal through the electroluminescent device, and then converted into a single current signal by superimposing the optical signal through the photosensitive component, the signal is not easy to crosstalk, has high stability, and can realize signals at different potentials. The superposition between them has a wide range of applications.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to a multi-channel current signal superposition device capable of superimposing different potential signals. Background technique [0002] Signal modulation technology is of great significance in the fields of video and audio transmission, wireless communication acquisition, system control, etc. With the rapid development of optical fiber sensing technology and optical fiber communication network technology, using signal modulation technology to control the current of semiconductor devices has become Become the current research direction and trend in this field. Modulation technology can make the modulated signal have strong anti-interference ability, and at the same time, it has little interference to adjacent channel signals, convenient demodulation and easy integration. Signal superposition is the basis of signal modulation technology. For example, in terms of video transmission, ...
