Abstract

Highlights: An optical limiter has exclusive importance in protecting light sensitive devices by suppressing undesired radiation. A variety of materials have been used as linearly absorbing media for optical limiting. Nonlinearities of materials play a key role in optical limiting processes. Reflection based optical limiter has manifested a new class of self-protecting optical limiters. Abstract: The optical limiting behavior of numerous nonlinear materials has been reviewed. Explicit examination of non-linear mechanisms such as multiphoton absorption, nonlinear absorption, nonlinear scattering and their peculiar implementation in optical devices using nonlinear materials as carbon nanotubes, fullerenes, semiconductors, graphene, and carbon black suspensions have been performed. Reflection-based optical limiters are especially emphasized for their self-protecting optical limiting over a broad transmission bandwidth. A comparative study of limiting parameters of several nonlinear materials is also included.
