Squeezing transfer of light in a two-mode optomechanical system
Optics Express
|May 5, 2019
Summary
This study shows how squeezed vacuum states can be transferred in optomechanical systems. Injected squeezed light significantly enhances output spectra and suppresses environmental noise.
Area of Science:
- Quantum Optics
- Optomechanics
Background:
- Optomechanical systems couple optical and mechanical degrees of freedom.
- Squeezed vacuum states offer non-classical light properties for enhanced measurements.
Purpose of the Study:
- Investigate the transfer of squeezing from an injected squeezed vacuum to an optomechanical cavity's output spectrum.
- Analyze the impact of environmental temperature on the output spectrum.
Main Methods:
- Theoretical investigation of squeezing transfer in a coupled optomechanical system.
- Calculation of the output field's noise spectrum.
Main Results:
- Observed two symmetrically located squeezing dips in the output spectrum.
- Identified major squeezing transfer from the injected squeezed vacuum.
- Demonstrated suppression of environmental temperature effects by the squeezed field.
Conclusions:
- Squeezing transfer is a viable mechanism in optomechanical systems.
- Injected squeezed vacuum enhances spectral properties and mitigates thermal noise.
- Potential applications in quantum communication using optomechanical interfaces.

Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

01:16Focusing of Light in the Eye
5.3K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...
