Optical spectral asymmetry enables differential refractive-index sensing under near-perfect common-mode suppression in a single-cavity dual-comb fiber laser
Single-cavity dual-comb fiber lasers offer near-perfect common-mode suppression, but such suppression is generally expected to eliminate differential sensing signals.Nondestructive 3D Metrology of Through-Glass Via Geometry and Internal Wall Texture Using Holotomography
Through-glass vias (TGVs) are increasingly important for semiconductor packaging, yet their internal geometry and wall texture remain difficult to characterize nondestructively.Experimental demonstration of response-enhanced fiber Sagnac gyroscopy via imaginary weak-value amplification
We experimentally demonstrate a 100-m long fiber Sagnac gyroscope employing imaginary weak-value amplification (IWVA) to enhance the optical readout response to rotation.Ultra-broadband quantum infrared spectroscopy extending to 20 {\textmu}m
Quantum infrared spectroscopy (QIRS), which exploits quantum interference between photon-pair generation processes, enables infrared spectroscopy using only visible and near-infrared (VNIR) light…Discovering Models for Experimental Quantum Systems with Agentic AI
A central obstacle in realizing color center cavity-QED-based quantum technologies is inhomogeneity, or disorder, among individual emitters.Non-Hermitian Theory of Surface Emitting Jackiw-Rebbi States
Topological interface states in open photonic systems combine spatial localization at domain walls with temporal confinement characterized by a radiative quality factor.Energy-Centroid Trembling near Exceptional Points in Photonic Time Crystals
In a photonic time crystal with a modulated Lorentz restoring coefficient, modulation reweights the potential energy of the polarization and loss drains its kinetic energy; when these sectors are…Semi-classical analysis of noise squeezing in Kerr microresonators
Kerr microresonators are integrated nonlinear devices widely used to generate classical optical frequency combs and nonclassical states of light.Unlocking Low-Frequency Laser Doppler Holography Spectra for Functional Retinal and Choroidal Microvascular Phenotyping
The low-frequency part of optical fluctuation spectra recorded by laser Doppler holography at a frame rate of 37~kHz is typically filtered out to reveal functional blood-flow waveforms in major…Quantitative Analytical Spheroid Model for Scattering-Type Scanning Near-Field Optical Spectroscopy of Layered Samples
Scattering-type scanning near-field optical microscopy (s-SNOM) is a versatile tool for probing optical properties at deeply subwavelength scales.Chiral Unidirectional Resonances Enabled by Complete Coherent Radiation Control
Optical resonances are commonly characterized by their quality factors, while their radiation exhibits richer properties associated with polarization and directional selectivity.Optimal Fan-Out and Break-Even Routing Loss in Waveguide-Integrated Ge-on-Si SPAD Arrays
Splitting a waveguide mode over several Ge-on-Si single-photon avalanche diodes (SPADs) relieves dead-time saturation but multiplies dark counts.Nonlinear Dynamics in Periodically Distributed Fibre Amplification Systems
We investigate effects of longitudinally varying nonlinearity on periodically distributed amplification systems in optical fibres.Optical Magnetic-Field Gating of Photon Avalanching Quantum Processes
Highly nonlinear phenomena, where macroscopic changes are triggered by microscopic perturbations, are ubiquitous in complex systems ranging from epidemic spreading to neural networks.Pump-scheme dependence of few-emitter lasers: exact multilevel correlations and photon statistics
Few-emitter laser models usually replace the excitation cycle of the gain medium by a single Markovian pump jump of a two-level emitter.Relaxation characteristics and spectral compression in the system of coupled radiating oscillators
The electromagnetic response of two identical coupled oscillators to an ultrashort pulse is investigated.Spectral Information Content of Diffraction-Limited Images
High-resolution optical imaging is fundamentally limited by diffraction, which imprints wavelength-dependent structure onto the point spread function (PSF) of the optical system.Quantum Advantage in Beam-Displacement Estimation for Inter-Satellite Quantum-Secure Time Transfer
In this work, we investigate the practical feasibility of achieving a quantum advantage, in the context of inter-satellite quantum communication, of satellite position estimation.Intensity-Domain Demultiplexing of Orbital Angular Momentum Channels for Optical Communication
Orbital angular momentum (OAM) multiplexing has been limited in practice by the complexity and optical loss of the elements that separate the channels at the receiver side.Non-contact temperature sensing and optical scatter in cryogenically-cooled crystalline silicon
Cryogenic crystalline silicon is a promising optical material for next generation gravitational-wave detectors due to its low mechanical loss (a driver of thermal noise), high thermal conductivity…
