Researchers analyze how quantum vacuum fluctuations can drive macroscopic switching in a biased degenerate optical parametric oscillator, and how an external bias field can reshape the system’s bistable landscape. The work offers a clearer picture of noise-assisted dynamics relevant to photonic computing and probabilistic quantum hardware.

A new differentiable design study shows how a phase-induced amplitude apodisation Zernike wavefront sensor can capture more starlight and improve sensitivity for extreme adaptive optics, especially in photon-starved and partially resolved-star conditions.

Researchers have demonstrated an all-optical in situ technique for timing the emission of high-order harmonics by introducing a delayed, cross-polarized replica of the driving infrared pulse. The approach, called HORNET, uses a weak ellipticity perturbation and ptychographic retrieval to reconstruct individual harmonic fields and their temporal profiles.

Researchers report a monolithic silicon nitride photonic platform that combines on-chip photon-pair sources, fusion circuits, and state-analysis interferometers with very low optical loss, improving the practicality of discrete-variable quantum information processing.

Researchers have used a programmable photonic mesh lattice to study open quantum-walk dynamics with tunable dephasing and non-reciprocal gain-loss imbalance, showing how decoherence can reshape directional transport in the Liouvillian regime.

A new nonlinear wide-field microscopy approach can directly probe in-plane components of propagating surface phonon polaritons, offering photonics researchers a complementary route to conventional near-field imaging and a faster path to vector-field studies in nanophotonics.

A new phase diversity approach combines a convolutional neural network with L-BFGS refinement to accelerate wavefront reconstruction for high-power laser systems while preserving calibration accuracy.

A new arXiv study explores whether score-based diffusion priors can guide Richardson–Lucy deconvolution, reducing noise amplification while preserving faint biological structures in low-photon fluorescence microscopy.
