Magneto‐plasmonic “switch” device for magnetic field detection

Nanophotonics, Volume 13, Issue 19, Page 3689-3698, August 2024.
Abstract This paper introduces a novel class of low‐loss and cost‐effective optical planar structures tailored for magnetic detection applications. These structures represent unconventional magneto‐plasmonic devices specifically optimized for an ‘optical switch’ configuration.

Magneto-optic Kerr effect CCD imaging with polarization modulation technique

AIP Advances, 2017
We have developed a magneto-optic Kerr effect (MOKE) imaging system with a charge-coupled-device (CCD) camera by using the rotating compensator technique. We chose optimal conditions of the rotation frequency of the compensator with stable rotation along

Quasi-Phase-Matched Faraday Rotation in Semiconductor Waveguides With a Magnetooptic Cladding for Monolithically Integrated Optical Isolators

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.

Giant Modulation of the Second Harmonic Generation by Magnetoelectricity in Two‐Dimensional Multiferroic CuCrP2S6

Advanced Materials, Volume 36, Issue 21, May 23, 2024.
Symmetries and magnetoelectric responses of van der Waals multiferroic CuCrP2S6 are investigated by second harmonic generation (SHG). Structural and magnetic phase transitions are successfully probed. The polarization dependence of the SHG signals is significantly modified, and the signal magnitude is enhanced by one order of magnitude under a finite ...

Magnetic Domain Wall Networked Films – Configurational Switching for Tunable Magnetization Dynamics by Perforated Thin Films

Advanced Materials Technologies, Volume 9, Issue 7, April 4, 2024.
Deterministic bi‐modal switching of magnetic precession frequencies of magnetic thin films is achieved by manipulating networks of magnetic domain walls through magnetic film perforation. The spatial mechanism is elucidated using dynamic magneto‐optical Kerr microscopy.

GAGA for nonreciprocal emitters: genetic algorithm gradient ascent optimization of compact magnetophotonic crystals

Nanophotonics, Volume 13, Issue 5, Page 773-792, March 2024.
Abstract Fundamental limits of thermal radiation are imposed by Kirchhoff’s law, which assumes the electromagnetic reciprocity of a material or material system. Thus, breaking reciprocity can enable breaking barriers in thermal efficiency engineering.

A Magnetoelastic Twist on Magnetic Noise: The Connection with Intrinsic Nonlinearities

Advanced Functional Materials, Volume 34, Issue 9, February 26, 2024.
Magnetoelastic nonlinearity significantly limits the performance of devices that use ferromagnetic films as sensitive elements. By introducing a comprehensive theory of magnetic noise in sensor systems, previously unrecognized noise sources linked to magnetoelasticity are revealed.
