Revisit the Poynting vector in PT-symmetric coupled waveguides
Xin-Zhe Zhang, Ru-Zhi Luo, Jing Chen
We show that the time-averaged Poynting vector in parity-time (PT ) symmetric coupled waveguides is always positive and cannot explain the stopped light at exceptional points (EPs)…
Farey tree and devil's staircase of frequency-locked breathers in ultrafast lasers
Xiuqi Wu, Ying Zhang, Junsong Peng +3
Nonlinear systems with two competing frequencies show locking or resonances. In lasers, the two interacting frequencies can be the cavity repetition rate and a frequency externally…
Stable high-dimensional weak-light soliton molecules and their active control
Lu Qin, Chao Hang, Boris A. Malomed +1
Bound states of solitons, alias soliton molecules (SMs), are well known in one-dimensional (1D) systems, while making stable bound states of multidimensional solitons is a challeng…
Interference of the scattered vector light fields from two optically levitated nanoparticles
Yuanbin Jin, Jiangwei Yan, Shah Jee Rahman +2
We experimentally study the interference of dipole scattered light from two optically levitated nanoparticles in vacuum, which present an environment free of particle-substrate int…
Sensitive label-free and compact ultrasonic sensor based on double silicon-on-insulator slot micro-ring resonators
Cheng Mei Zhang, Chao Ying Zhao
We propose a new label-free ultrasonic sensor, which comprises a slot wave-guide and double silicon-on-insulator (SOI) slot micro-ring resonators. The all-optical sensors do not su…
Numerical analysis of effective refractive index ultrasonic sensor based on Cantilever arm structure slot-based dual-micro-ring resonator
C. Y. Zhao, P. Y. Li, C. M. Zhang
We propose a novel ultrasonic sensor structure composed of Cantilever arm structure slot dual-micro-ring resonators(DMRR).We present a theoretical analysis of transmission by using…
