Abstract

The invention discloses an optical signal time-to-space conversion device and method. The device comprises several same reflectors with diameters of d, a laser source system for producing parallel light, a spatial light modulator and a light splitting prism. According to the number of light paths needing to be output in parallel, a reflector system composed of the several reflectors is designed and a light path is built and debugged. The parallel light produced by the laser source system goes through the light splitting prism, then irradiates the spatial light modulator loaded with serially-transmitted data, and is modulated by the spatial light modulator so that the parallel light is loaded with the serial data. The parallel light reflected by the spatial light modulator goes through the light splitting prism again and then goes into the reflector system and the parallel light going through the reflector system is in a parallel data transmission mode.

Description

technical field [0001] The invention relates to a time-space conversion of optical signal transmission, in particular to a brand-new method for realizing the time-space conversion of optical signals by using a mirror system. Background technique [0002] Optical information processing is a new subject developed in recent years. The subject develops rapidly and has become an important branch of information science. Compared with other forms of information processing technology, the advantages of optical information processing lie in its high degree of parallelism and large capacity. Generally, the input optical signal for optical information processing is converted from an electrical signal. Usually, the data transmission mode of the electrical signal is serial, and the input optical signal thus converted is also serial. In order to achieve a high degree of parallelism in optical information processing, it is meaningful and crucial to perform serial-to-parallel conversion of...
