This paper presents a phase-sensitive tip-enhanced sum frequency generation spectroscopy technique that utilizes temporally asymmetric pulses to suppress non-resonant background interference, thereby achieving nanoscale spatial resolution and enabling the detection of weak vibrational signals and determination of absolute molecular orientations at surfaces.
This paper presents a hybrid jump-diffusion stochastic model that successfully reproduces the temperature-dependent spectral diffusion and coherence degradation of quantum emitters in hexagonal boron nitride (hBN), establishing a unified phenomenological framework that links noise mechanisms to optical coherence limits and predicts a critical crossover to overdamped dynamics at approximately 25.91 K.
This study demonstrates that self-assembled CsPbBr3 quantum dot superlattices exhibit room-temperature collective blinking and photon bunching driven by exciton-biexciton cascade emission, establishing them as a scalable platform for quantum light generation and many-body optical phenomena.
This paper introduces an all-optical imaging modality that achieves 100-attosecond temporal and 200-nanometer spatial resolution to directly visualize the spatiotemporal evolution and vector electric field lines of light within a widefield transmission microscope, enabling the observation of ultrafast scattering dynamics and pulse broadening in MoTe2 that are inaccessible via standard simulations.
This paper presents a scalable, monolithic fabrication strategy that integrates high-stress silicon nitride membranes with distributed Bragg reflectors using dry processing techniques, achieving self-aligned optomechanical cavities with high optical finesse and mechanical quality factors while eliminating the alignment and stability bottlenecks of conventional methods.
This paper demonstrates a low-confinement silicon nitride photonic platform integrated with piezo-optomechanical actuators that achieves ultra-low propagation losses of 0.026 dB/cm at visible wavelengths, enabling scalable quantum circuits with high-performance active functionality.
This study demonstrates that embedding a single GaAs quantum dot in a dielectric metasurface enables simultaneous anti-bunched and super-bunched photon emission from neutral and charged exciton complexes, respectively, by enhancing weak charged exciton transitions to achieve comparable count rates.
This paper generalizes an all-optical telecorrection protocol for higher-order cat codes, demonstrating that they achieve target performance with substantially reduced iteration counts at the cost of increased mean photon numbers, while also introducing a probabilistic scheme to correct state deformation and change the code basis.
This paper demonstrates a single-pass, unfiltered source of hyperentangled photon pairs in polarization and frequency-bin degrees of freedom at telecom wavelengths, achieved by optically tailoring the joint spectral amplitude via pump and nonlinearity shaping to enable tunable state dimensions with high fidelities.
This paper provides a comprehensive review of analogue Hawking radiation in nonlinear quantum optics, outlining the theoretical concepts of the gravitational analogy and chronicling the timeline of key fiber-optical experiments from 2008 to the present.
