Bright squeezed light field producing device

Abstract

The invention discloses a bright squeezed light field producing device. The bright squeezed light field producing device is characterized by being provided with an inner-cavity coherent population trapping (CPT) effect system, the inner-cavity CPT effect system is provided with a first light source and a second light source, the first light source is a bright squeezed laser source, and the secondlight source is a coherent laser source. The inner-cavity CPT effect system is provided with double resonant optical resonators, and artificial atoms are built in the double resonant optical resonators. The first light source and the second light source are simultaneously resonant with the optical resonators and produce a resonance effect with two transition energy levels of the artificial atoms to form a Lambda type three-energy-level structure, an inner-cavity CPT effect is achieved, conversion from quantum compression characteristics of the first light source to the second light source is completed, and preparation of a bright squeezed light field is achieved. The bright squeezed light field producing device is compact in structure and easy to operate, other different wavelengths of squeezed light can be prepared based on existing squeezed light, accordingly the wavelength range of the squeezed light is widened, and the bright squeezed light field producing device has the importantapplication value in the fields such as precision quantum measurement and quantum communication.

AI Technical Summary

Benefits of technology

This patented method allows for creating an optical device called Quantum Interface (QI) without requiring complex materials or processes. It achieves this by combining different types of particles into a single entity like atomic molecules. By adjusting certain parameters such as particle size, shape, material composition, etc., it becomes possible to achieve specific desired properties within these systems.

Problems solved by technology

Technologies described in this patents involve creation or manipulation of special types of lights called optofluorescences (OFs) due to their unique properties such as long lifespan, stable emission over wide wavelength ranges, ability to absorb specific colors from visible rays, potential applications like sensors, displays, and communications devices. These technics have advanced science and engineering capabilities but require precise alignment between different parts within the lasers' structure.
