Controlling photonic spin Hall effect via exceptional points
Xinxing Zhou, Xiao Lin, Zhicheng Xiao +4
The photonic spin Hall effect (SHE), featured by a spin-dependent transverse shift of an impinging optical beam driven by its polarization handedness, has many applications includi…
Highly-Linear Magnet-Free Microelectromechanical Circulators
Yao Yu, Giuseppe Michetti, Ahmed Kord +6
This paper reports the first demonstration of a magnet-free, high performance microelectromechanical system (MEMS) based circulator. An innovative circuit based on the commutation…
Radio Frequency Magnet-free Circulators Based on Spatiotemporal Modulation of Surface Acoustic Wave Filters
Yao Yu, Giuseppe Michetti, Michele Pirro +6
In this paper, a new generation of magnet-free circulators with high performance is proposed. Circulators are crucial devices in modern communication systems due to their ability t…
Broadband Cyclic-Symmetric Magnet-less Circulators and Theoretical Bounds on their Bandwidth
Ahmed Kord, Dimitrios L. Sounas, Zhicheng Xiao +1
In this paper, we explore theoretically and experimentally broadband spatiotemporally modulated (STM) magnet-less circulators realized by combining three-port non-reciprocal juncti…
Non-reciprocal Components Based on Switched Transmission Lines
Aravind Nagulu, Tolga Dinc, Zhicheng Xiao +4
Non-reciprocal components, such as isolators and circulators, are critical to wireless communication and radar applications. Traditionally, non-reciprocal components have been impl…
Goos-Hänchen and Imbert-Fedorov Shifts of Vortex Beams at Air-Left-Handed Material Interfaces
Zhicheng Xiao, Hailu Luo, Shuangchun Wen
In this paper, we present a systematic study of beam shifts and angular momenta of paraxial vortex beams at air-left-handed material (LHM) interfaces. It is shown that, compared to…
Experimental observation of the spin Hall effect of light on a nano-metal film via weak measurements
Xinxing Zhou, Zhicheng Xiao, Hailu Luo +1
We theorize the spin Hall effect of light (SHEL) on a nano-metal film and demonstrate it experimentally via weak measurements. A general propagation model to describe the relations…
