IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations

IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations

Identical bonds within a polyatomic group can stretch symmetrically (in-phase) or asymmetrically (out-of-phase). Similar to hydrogen bonding, these vibrations also influence the shape of the IR peak. Generally, asymmetric stretching frequencies are higher than symmetric stretching frequencies. For example, primary amines exhibit two distinct IR peaks between 3300–3500 cm−1 corresponding to the symmetric and asymmetric N-H stretching, while secondary amines exhibit a single...

The Squeeze Theorem

The Squeeze Theorem

Certain mathematical functions exhibit unpredictable or highly variable behavior near specific input values, making direct evaluation of their limits challenging. This complexity may arise from rapid oscillations or irregular patterns that obscure the function’s trend. In such cases, the Squeeze Theorem offers a reliable method for determining limits.According to the Squeeze Theorem, if a function is confined between two other functions near a particular point, and both outer functions...

What is a Mode?

What is a Mode?

The mode is one of the commonly used measures of a central tendency. It is defined as the most frequent value in a data set.
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...

MOSFET: Enhancement Mode

MOSFET: Enhancement Mode

Enhancement-mode MOSFETs are pivotal components in electronics, distinguished by their capacity to act as highly efficient switches. They are part of the larger family of metal-oxide Semiconductor Field-Effect Transistors (MOSFETs). They are available in two types: p-channel and n-channel, each tailored to specific polarity operations.
In their basic form, enhancement-mode MOSFETs are typically non-conductive when the gate-source voltage (Vgs) is zero. This default 'off' state means no...

Background:

Squeezed states of light are crucial for quantum technologies.
Tailoring the spatial modes of squeezed light is essential for specific applications like imaging and metrology.
Previous methods were limited in generating diverse squeezed spatial modes.

Purpose of the Study:

To demonstrate the generation of single-mode squeezed light in various spatial modes (Laguerre-Gauss, Bessel-Gauss) and arbitrary patterns.
To showcase the capability of a single experimental setup for flexible spatial reshaping of squeezed light.
To validate the use of spatial light modulators (SLMs) for advanced quantum optical experiments.

Main Methods:

Utilized a spatial light modulator (SLM) to control the spatial mode of squeezed light.
Generated single-mode squeezing in Laguerre-Gauss and Bessel-Gauss modes.
Measured the degree of squeezing and analyzed noise contributions.

Main Results:

Successfully generated squeezed light in multiple spatial modes and arbitrary intensity patterns from a single setup.
The degree of squeezing was primarily limited by initial squeezing and SLM-induced diffractive losses.
No excess noise was detected from the SLM at the measured sideband.

Conclusions:

Spatial light modulators (SLMs) are viable and flexible tools for spatially reshaping squeezed light.
The experiment confirms the single-mode squeezing concept in quantum optics.
This technique opens new possibilities for tailoring squeezed light for diverse quantum applications.
