Abstract

The invention provides a method and device for realizing multifunctional optical time-domain stealth and event editing, and belongs to the fields of optical communication and optoelectronic devices. The invention overcomes the disadvantages of the existing optical time-domain cloaks, such as complex structure, complicated operation process and special devices, and adopts a new method of time-domain division and backfilling to realize the time-domain optical cloak, and the realization mechanism is simple. In addition to stealth, it also implements other functions such as event deletion and rewriting, and can flexibly switch between different functions. In terms of implementation, the components commonly used in optical communication such as optical switches and modulators are used, which greatly reduces the complexity and implementation cost of the system, and can avoid the dependence on high-power devices, so it has strong practical operability .

Description

technical field [0001] The invention belongs to the field of optical communication and optoelectronic devices, in particular to a method and device for realizing multifunctional optical time-domain stealth and event editing. Background technique [0002] Due to the novelty of the concept and its important applications in visual imaging and electromagnetic transmission, the invisibility cloak has not only been a magical prop in science fiction and film and television dramas, but also has become a research hotspot in the field of electromagnetics since its conception was proposed. The invisibility cloak in the space domain, which has been studied more in recent years, refers to some kind of covering or wrapping that is artificially made, and its function is to make the objects in the covered or wrapped space invisible to the detection electromagnetic waves of a certain band. [0003] However, the concept of time-domain invisibility cloak that appeared recently is different fro...
