Quasi-Phase-Matched Faraday Rotation in Semiconductor Waveguides With a Magnetooptic Cladding for Monolithically Integrated Optical Isolators [PDF]
IEEE Photonics Journal, 2013 Strategies are developed for obtaining nonreciprocal polarization mode conversion, also known as Faraday rotation, in waveguides in a format consistent with silicon-on-insulator or III-V semiconductor photonic integrated circuits.

Event-based vision in magneto-optic Kerr effect microscopy
AIP Advances, 2022 Magneto-optic Kerr effect (MOKE) microscopy is a widely used technique for observation and characterization of microscopic magnetic structures. While being efficient and easy-to-use, current commercial MOKE microscopes are not superb in time resolution ...

Emulation of magneto-optic Faraday effect using ultracold atoms
New Journal of Physics, 2021 We propose an arresting scheme for emulating the famous Faraday effect in ultracold atomic gases. Inspired by the similarities between the light field and bosonic atoms, we represent the light propagation in medium by the atomic transport in accompany of

Multiphoton Magnetooptical Trap [PDF]
Physical Review Letters, 2009 We demonstrate a magnetooptical trap (MOT) configuration which employs optical forces due to light scattering between electronically excited states of the atom. With the standard MOT laser beams propagating along the x and y directions, the laser beams along the z direction are at a different wavelength that couples two sets of excited states.

Advanced Engineering Materials, Volume 25, Issue 21, November 2023., 2023 Solidly mounted resonator (SMR) magnetoelectric (ME) antennas at 1.75 GHz are successfully fabricated, exhibiting an antenna gain of −18.8 dBi and a 1 dB compression point (P1dB) of 30.4 dBm. The 23.3 dB higher power handling capability than same‐size thin‐flm bulk resonator ME antenna significantly enhances robustness; manageable complementary metal ...

Extreme anti-reflection enhanced magneto-optic Kerr effect microscopy
Nature Communications, 2020 Magneto-optic Kerr effect microscopy is useful for dynamic magnetic studies, but is limited by the weak magneto-optical activity. Here, the authors show that extreme anti-reflection result in a Kerr amplitude as large as 20° and enables real-time ...
