Summary
Delayed optical feedback in quantum-dot microlasers controls complex dynamics and reduces stochastic switching. This research enhances understanding and control of microlaser emission properties for nanophotonics applications.
Area of Science:
- Quantum optics
- Nonlinear dynamics
- Nanophotonics
Background:
- Microlasers offer a platform for exploring complex nonlinear dynamics in quantum optics.
- Tailoring microlaser emission via delayed optical coupling is highly desirable but underexplored.
Purpose of the Study:
- Investigate the impact of delayed optical feedback on the mode-switching dynamics of electrically driven bimodal quantum-dot micropillar lasers.
- Characterize feedback effects on output power, optical spectrum, and photon statistics.
Main Methods:
- Experimental and theoretical analysis of delayed optical feedback.
- Utilized an electrically driven bimodal quantum-dot micropillar laser.
Main Results:

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

The Quantum-Mechanical Model of an Atom

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Switching of BJT

Switching behavior in Bipolar Junction Transistors (BJTs) is a fundamental aspect utilized in various electronic circuits, particularly for digital logic applications like switches and amplifiers. In a typical switching circuit, a BJT alternates between cut-off and saturation modes, corresponding to the "off" and "on" states, respectively, thus behaving like an ideal switch.

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

What is a Mode?
26.3K
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,...
