Non-Linear Localized Modes Give Rise to a Reflective Optical Limiter

TL;DR

This paper introduces a novel layered reflective optical limiter that uses non-linear localized modes to reflect high-intensity light, avoiding absorption and overheating, applicable across various frequencies and incident angles.

Contribution

The paper presents a new concept of a layered reflective limiter based on resonance transmission through non-linear localized modes, differing from traditional absorptive limiters.

Findings

Reflects high-intensity light over a broad frequency range

Operates effectively for arbitrary incident directions

Applicable to infrared and microwave frequencies

Abstract

Optical limiters are designed to transmit low intensity light, while blocking the light with excessively high intensity. A typical passive limiter absorbs excessive electromagnetic energy, which can cause its overheating and destruction. We propose the concept of a layered reflective limiter based on resonance transmission via a non-linear localized mode. Such a limiter does not absorb the high level radiation, but rather reflects it back to space. Importantly, the total reflection occurs within a broad frequency range and for an arbitrary direction of incidence. The same concept can be applied to infrared and microwave frequencies.
