Variable Focus Nonlinear Lens via Transformation Optics

TL;DR

This paper introduces a nonlinear lens structure that can switch between light concentration and variable focusing modes by adjusting incident light intensity, enabling dynamic control of light manipulation.

Contribution

It presents a novel nonlinear lens design with a graded-index shell that dynamically switches functions based on light intensity, advancing adaptive optical device technology.

Findings

The structure effectively switches between concentration and focusing modes.

The lens's focus can be tuned by varying incident light intensity.

Demonstrates potential for dynamic optical applications.

Abstract

We propose a structure consisting of nonlinear core and graded-index shell that can be switched from a concentrator squeezing light into the core to a variable focus lens by varying the intensity of incident light.
