We cascade VO2-based tunable optical cavities with selective-transparent layers to overcome the wavelength dependence, realizing the multispectral manipulation with reversible tunability covering wavelengths ranging from the VIS to MW regions.
The centrally located reciprocal point can achieve single-mode transmission and switch off the photonic molecule. The deviated reciprocal point can switch on the photonic molecule and dynamically control the splitting.
A novel generic high-fidelity Raman spectral denoising and baseline correction strategy to enhance diverse cross-device/specimen biomedical applications and hyperspectral image chemical resolution visualization to reveal spatial features of cancer tissue.
We develop a wearable and interactive multicolored photochromic fiber using the thermal drawing technique, which overcomes the dependence on external light sources and the non-uniform light emission observed in polymer optical and photochromic fibers.
The theoretical unlimited orbital angular momentum states have been utilized as node signals in an optical neural network to implement machine learning tasks.
Strong effective photon–photon interactions (Kerr-like optical nonlinearity) via the Rydberg blockade phenomenon in Cu2O-microcavity achieved under pulsed resonant excitation enabling fundamental studies of strongly correlated polaritonic states and quantum optical applications.
Hybrid Rayleigh-Brillouin-Raman distributed sensing system: Coded pulse pairs are employed for simultaneously measuring vibration, strain and temperature distributions, through an optimized detection scheme of Rayleigh, Brillouin, and Raman scatterings.
The integration between vertical-cavity surface-emitting lasers and metasurfaces has been demonstrated to enable on-chip high-angle illumination for high-contrast microscopy, providing a versatile illumination module for biophotonics and life-science applications.
We propose a new type of classical optical convolutional neural network by introducing the optical correlation. Such a network can exhibit “quantum speedup”like the quantum neural networks.
