A novel class of solitons, which builds up in spectrally confined optical cavities when dispersion is practically absent, is revealed both theoretically and experimentally, opening new avenues for generating soliton pulses and frequency combs endowed with unprecedented temporal and spectral features.
We experimentally demonstrate the separation of wave and particle properties of a single photon inspired by quantum Cheshire cat via the weak measurement in the scheme of imaginary-time evolution.
With the development of optical technology, LCs with intelligent light protection function become more and more important. This paper discusses the research progress and challenges of LCs for light protection.
Rotation-angle-dependent phonon-assisted photon upconversion in twisted two-dimensional semiconductor is investigated. Lattice relaxation along with enhanced pump efficiency, lead to an inverted contrast between upconversion and conventional photoluminescence.
Wafer-scale phase-controlled 2D MoTe2 layers was synthesized for in-situ fabrication of room-temperature high-performance broadband infrared photodetector and device array.
Prof. Guangcan Guo took it upon himself to delve into quantum optics and quantum informatics, which helped to accelerate the development of quantum science in China.
We demonstrate that voids in high-index dielectrics support localized resonant modes which are confined in air and thus do not suffer from the loss and dispersion of the host medium
Colloidal quantum dot gradient homojunction would effectively improve the detectivity of mid-infrared photodetector at high-operating temperatures, motivating interest in low-cost, solution-processed and high-performance mid-infrared photodetection.
