Summary
Scar modes in chaotic wave billiards can be selected by gain. This study demonstrates scar mode selection by gain in a doped D-shaped optical fiber, exploiting their unique localization properties.
Area of Science:
- Nonlinear dynamics
- Quantum chaos
- Optical physics
Background:
- Chaotic wave billiards exhibit nongeneric spatially localized modes known as scar modes.
- The influence of gain on scar modes has been explored in optical microcavities and vertical-cavity surface-emitting lasers.
Purpose of the Study:
- To experimentally demonstrate scar mode selection by gain in a doped D-shaped optical fiber.
- To leverage the phase-space localization properties of scar modes for optical applications.
Main Methods:
- Utilizing a doped D-shaped optical fiber as the experimental platform.
- Exploiting the wave-analogous phase-space representation of scar modes.
- Applying gain to influence mode selection within the optical fiber.
Main Results:
- Successful experimental observation of scar mode selection mediated by gain.
- Demonstration of controlling spatially localized modes in a chaotic system.
- Validation of scar mode localization properties in an optical fiber setting.
Conclusions:
- Gain-induced scar mode selection is achievable in optical fibers.
- D-shaped optical fibers provide a viable system for studying scar modes.
- This work opens avenues for controlling light localization in optical devices.
