Giant Faraday rotation in atomically thin semiconductors [PDF]
Nature CommunicationsFaraday rotation is a fundamental effect in the magneto-optical response of solids, liquids and gases. Materials with a large Verdet constant find applications in optical modulators, sensors and non-reciprocal devices, such as optical isolators. Here, we

Omni-polarized Faraday isolator based on non-Hermitian Faraday system
Optics ExpressNon-Hermitian systems have recently attracted significant attention in photonics due to the realization that the interplay between gain and loss can lead to entirely new and unexpected features. Here, we propose and demonstrate a non-Hermitian Faraday system capable of non-reciprocal omni-polarizer action at the exceptional point. Notably, both forward

High-power Faraday isolators based on TAG ceramics
Optics Express, 2014 The Faraday isolator based on a new magneto-optical medium--TAG (terbium aluminum garnet) ceramics was implemented and investigated experimentally. The magneto-optical element was temperature-stabilized using water cooling. The device provides a stable isolation ratio of 38 dB at 300 W laser power.

Integrated Magnetless Passive Broadband Faraday Isolator [PDF]
, 2023 Abstract Optical isolation based on a non-reciprocal effect is crucial for proper operation of several high-performance photonic devices such as LiDAR and quantum platforms. The magneto-optical Faraday rotation is the most commonly used non-reciprocal effect as it offers unique advantages, including broadband operation, wide input optical power

Faraday Isolators for High Average Power Lasers
, 2010 The average power of solid-state and fiber lasers has considerably increased during the last ten years. The 10 kW power is not record-breaking any longer, and a topical problem nowadays is to create lasers with a power of 100 kW. Therefore, the study of thermal effects caused by absorption of laser radiation in the bulk of optical elements becomes ever

The Faraday Isolator, Detailed Balance and the Second Law
Journal of Applied Mathematics and Physics, 2017 A Faraday isolator is shown to develop a temperature difference between its input and output, but still complies with the second law when all the heat carriers, in this case, photons are homogeneous and indistinguishable. This result is a consequence of the H-theorem which assumes homogeneity and indistinguishability of particles.
