Abstract

The invention discloses a bacteriorhodopsin thin film-based sinusoidal modulation optically-controlled delayed opening and timing shutdown system, which comprises a 633nm laser (3-1), light intensity-adjustable attenuators (3-7, 3-8 and 3-10), a bacteriorhodopsin thin film material (3-9), photodetectors (3-11 and 3-12), an oscilloscope (3-13), a reflecting mirror (3-6), a semitransparent half-reflecting mirror (3-5), a 633nm laser (3-1), a signal generator (3-3), a photoelectric modulator (3-2) and a polarizer (3-4). By employing the optical control system, the signal is attenuated a little in the transmission process, the speed of a weak light group is reduced by 1mm / s at normal temperature, and the functions of opening after the optical information controlled delay time of 0.20 second and closing at fixed time of 1 to 20 seconds are realized.

Description

technical field [0001] The invention belongs to the field of light-controlled time-delay switch devices, and in particular relates to a light-controlled time-delayed opening and timing closing system based on a bacteriorhodopsin film, wherein a signal arrives at a delayed time and a transmission switch is opened, and the switch is closed after timing transmission of the signal. Background technique [0002] Bacteriorhodopsin (BR for short) is a photosensitive protein in the cell membrane of halophilic bacteria that is similar to rhodopsin in vision. The most excellent characteristics of BR film materials are photochromic performance, transient Photoelectric response performance and nonlinear optical performance have broad application prospects in the field of optical information processing) There are many studies on all-optical switches. Anisotropic characteristics and other principles realize all-optical switches; from the realization means, some use two-wave coupling or mu...
