We report the NOON-state interference in the frequency domain. Two photons with distinct colors, blue and red, are injected into an interferometer constructed with two frequency beam splitters. The resultant interference pattern is then observed.
This work explores the boundary between nanocrystal and relative bulk, expanding the photoresponse wavelength limitation of colloidal quantum dot photodetector up to very long wave infrared.
We report a crystalline host matrix with engineered nanoaggregate structure for fabricating high-performance crystalline white OLEDs (C-WOLED), showing its significant potential in developing the next-generation OLED technology.
Dual-channel mechano-phosphorescence, characterized by dual emission and ultralong organic phosphorescence, was achieved by strengthening the intra- and intermolecular interactions in the highly twisted structures to realize a combined locking effect.
The 3D density profile of a femtosecond kilo-ampere electron bunch from laser wakefield acceleration was detected by using advanced optical diagnostics and genetic algorithm.
We introduce an innovative quartz-enhanced multiheterodyne resonant photoacoustic spectroscopy technique that utilizes a quartz tuning fork to achieve resonant detection of a dual comb based on the photoacoustic effect.
We demonstrate free-space coupling to microtoroids using one objective to excite and collect scattered resonant light. We achieve Q-factors > 108 and perform sensing with an SNR > 26 dB.
We developed a geometric approach to identify highly anisotropic materials. This leads to the discovery of giant anisotropy of As2S3, enabling the record-small quarter-wave plate.
A time-domain excitation strategy for stimulated Raman scattering was achieved by manipulating vibrational wave packet interference. The new method enables simultaneous sub-mM level sensitivity and natural-linewidth-limit Raman spectra.
We have introduced Te-based all-2D heterojunctions as optically controlled terahertz modulators to significantly promote the device performances and elaborated their charge dynamics driven by substrate effect through first-principles calculations.
We explore an open trajectory linking two infinite points having the same asymptotic eigenmodes, demonstrating that this platform enables high-efficiency chiral transmission, with each eigenmode localized in a single waveguide.
