Recent advances and perspective of photonic bound states in the continuum
Guizhen Xu, Hongyang Xing, Zhanqiang Xue +5
Recent advancements in photonic bound states in the continuum (BICs) have opened up exciting new possibilities for the design of optoelectronic devices with improved performance. I…
The Underlying Mechanisms of Time Dilation and Doppler Effect in Curved Space-Time
Benliang Li, Hailiang Zhang, Perry Ping Shum
In this paper, we theoretically investigate the time dilation and Doppler effect in curved space-time from the perspective of quantum field theory (QFT). A Coordinate Transformatio…
Harnessing oversampling in correlation-coded OTDR
Ruolin Liao, Ming Tang, Can Zhao +4
Pulse coding is an effective method to overcome the trade-off between signal-to-noise ratio (SNR) and spatial resolution in optical-fiber sensing systems based on optical time-doma…
Exceptional Points in a Non-Hermitian Topological Pump
Wenchao Hu, Hailong Wang, Perry Ping Shum +1
We investigate the effects of non-Hermiticity on topological pumping, and uncover a connection between a topological edge invariant based on topological pumping and the winding num…
BOTDA using OFDM channel estimation
Can Zhao, Ming Tang, Liang Wang +7
A novel Brillouin optical time-domain analysis (BOTDA) system is proposed using intensity-modulated optical orthogonal frequency division multiplexing probe signal and direct detec…
Measurement of a topological edge invariant in a microwave network
Wenchao Hu, Jason Cornelius Pillay, Kan Wu +3
We report on the measurement of topological invariants in an electromagnetic topological insulator analog formed by a microwave network, consisting of the winding numbers of scatte…
Effects of carbon nanotubes and graphene oxide absorbers on the noise of mode-locked fiber lasers
Xiaohui Li, Kan Wu, Xuechao Yu +9
Phase noise is very important for the ultrafast pulse application in telecommunication, ultrafast diagnose, material science, and biology. In this paper, two types of carbon nano-m…
