Multi-stability and polariton solitons in microcavity wires
Optics Letters
|April 15, 2015
Summary
Nonlinear polaritons in microcavity wires show multi-stable behavior due to co-existing cavity modes. This study explores conditions for multi-mode polariton solitons and their propagation dynamics.
Area of Science:
- Condensed matter physics
- Quantum optics
- Photonics
Background:
- Microcavity wires support nonlinear polaritons, which are hybrid light-matter quasiparticles.
- These systems can exhibit complex dynamics and multi-stability.
Purpose of the Study:
- To investigate the origins of multi-stability in nonlinear polaritons within microcavity wires.
- To analyze the conditions for the formation and stability of multi-mode polariton solitons.
- To study the propagation dynamics of solitons in tilted microcavity wires.
Main Methods:
- Theoretical analysis of nonlinear polariton dynamics.
- Numerical simulations of polariton behavior in microcavity structures.
- Investigation of modulational stability and soliton formation.
Main Results:
- Multi-stability arises from the coexistence of different transverse cavity modes.
- Conditions for stable multi-mode polariton solitons were identified.
- Soliton propagation was demonstrated in tilted microcavity wires, with a critical tilt angle observed.
Conclusions:
- The interplay of transverse cavity modes is crucial for multi-stability in nonlinear polaritons.
- Multi-mode polariton solitons can be formed and propagated under specific conditions.
- Tilted microcavity geometries introduce new dynamics and limitations for soliton propagation.

01:28Standing Waves in a Cavity
1.7K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...

A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

The transfer function is a fundamental concept representing the ratio of two polynomials. The numerator and denominator encapsulate the system's dynamics. The zeros and poles of this transfer function are critical in determining the system's behavior and stability.
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's...

Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...
