Enhanced microwave-atom coupling via quadrupole transition-dressed Rydberg atoms
Frontiers in PhysicsThe power broadening of a coupling laser can be converted into two-photon detuning by electromagnetically induced transparency (EIT), resulting in a residual Doppler effect.

Magneto-Optical Devices for Optical Integrated Circuits [PDF]
, 2010 We have demonstrated that magneto-optical materials are important for optoelectronics, because of their unique non-reciprocal and memory properties. At present, there is an industrial demand for a waveguide-type optical isolator and a high-speed non-volatile optical memory.

Electro-Optic Plasmonic Modulator With Direct Coupling to Silicon Waveguides
IEEE Photonics Journal, 2017 A novel plasmonic Mach–Zehnder interferometer is proposed with a nonlinear polymer. Orthogonal junction coupling between silicon and plasmonic waveguides is exploited to omit the need for tapers, and in turn, reduce the footprint.
