Problems solved by technology

[0004] At present, the existing time-domain cloaking devices are signal-source-type time-domain cloakers, that is, the time-domain cloaking is performed on the event signal at the sending end, which leads to the lack of flexibility in the deployment of the existing signal-source-type time-domain cloaking devices, and the existing There are other technical problems in the application of time-domain cloaking devices, including: complicated implementation, large volume and difficulty in integration

Embodiment Construction

[0065] The present invention will be further described in conjunction with accompanying drawing and example now.

[0066] Such as figure 1 As shown, the present invention provides a transparent, adaptive line-type optical time domain cloaking device, which can be flexibly deployed on links that require time domain cloaking, and does not require additional and can also automatically match the input optical signal and the output optical signal pulse shape, wavelength and power, so that the sending end and the receiving end are not aware of the device of the present invention inserted in the middle of the link, so the device of the present invention has a great impact on the link. It is transparent, and the matching process does not require manual settings by personnel, so the device of the present invention has an adaptive function. In addition, the device of the present invention has the advantages of simple implementation, small volume and easy integration.

Abstract

The invention belongs to the technical field of optical communication and optoelectronic devices, and particularly relates to a transparent and self-adaptive line type optical time domain stealth device which is provided with one path of input optical signals, one path of output optical signals and one path of stealth control signals. The input optical signal is input to the optical time domain stealth device, the stealth control signal controls stealth of the input optical signal, and the stealthy signal is output as an output optical signal; the stealth device can be flexibly arranged at any position of a transmission link, the optical wavelength, the pulse shape and the optical power of signals of the transmission link are not changed while time domain stealth of output signals is achieved, the stealth device has the transparent characteristic to a physical layer, the function of transparency to the physical layer is achieved through self-adaptive matching of the stealth device, and manual setting is not needed.

Description

technical field [0001] The invention belongs to the technical field of optical communication and optoelectronic devices, and in particular relates to a transparent, self-adaptive line-type optical time-domain cloaking device and a cloaking method. Background technique [0002] Stealth technology is to prevent observers from observing the existence of targets, including two dimensions of airspace stealth and time domain stealth. Among them, airspace stealth is to hide the space target from the detector, and the way to realize it is to change the transmission direction of the detection light around the space target, so that the detection light does not interact with the space target, and restore the transmission direction of the detection light after passing the space target, so that Detectors cannot observe the existence of space objects. Temporal cloaking is to hide events that occur in the time dimension, so that observers cannot perceive that events "ever" happened. Sinc...
