Abstract

The invention provides an electrically-controlled resonant coupled artificial surface plasmon cascaded slow light device, which comprises a dielectric substrate which is printed with an artificial surface plasmon transmission line; at least one group of functional units are arranged in the transmission direction of the artificial surface plasmon transmission line; each group of function units comprises bright and dark mode resonance structure pairs symmetrically distributed on two sides of the transmission direction of the artificial surface plasmon transmission line, and each bright and dark mode resonance structure pair comprises a bright mode resonance structure arranged on the inner side and a dark mode resonance structure arranged on the outer side; a PIN diode is arranged on the dark mode resonance structure, and mutual coupling between the dark mode resonance structure and the dark mode resonance structure is controlled by controlling the on-off state of the PIN diode, so that the group velocity and the propagation characteristic of the artificial surface plasmon are changed; the invention has the beneficial effect of dynamic tuning, and is suitable for the field of slow light devices.

Description

technical field [0001] The invention relates to the technical field of slow light devices, in particular to an electrically controlled resonance coupled artificial surface plasmon cascade slow light device. Background technique [0002] Slow light refers to the phenomenon that light propagates in the medium at a slower group velocity under certain specific conditions and medium structures. It is considered to be the most potential of all-optical communication and quantum information processing technology to realize the functions of optical cache and optical switch. In the prior art, a special structure is designed to achieve slow light by changing the dispersion coefficient of the material or starting from the structure of the material, but the use value of the solution is limited due to the fixed structure. [0003] Since slow light enhances the light intensity, another very important application of slow light is to enhance the interaction between light and matter per unit ...
