Gain-through-filtering enables tuneable frequency comb generation in passive optical resonators

In normal dispersion, modulation instability, which is a precursor of Kerr combs, is forbidden due to phase mismatch. Here, the authors show the compensation of such phase mismatch by introducing frequency-dependent loss using a notch filter, hence leading to effective parametric gain and comb formation.

The piston Riemann problem in a photon superfluid

The flow of light in nonlinear media can be considered as superfluid flow and described with quantum hydrodynamics. Here the authors demonstrate superfluid flow, optical rarefaction (retracting piston) and shock (pushing piston) wave pairs and characterize associated phase transitions by using fiber-based platform.

Brillouin-induced Kerr frequency comb in normal dispersion fiber Fabry Perot resonators

Optical frequency combs are key tools in spectroscopy and telecom. Here, authors report a stable and broadband comb (>10 THz) from a high-Q fiber Fabry-Perot resonator via Kerr-Brillouin passive mode-locking. This easily integrable platform ensures state-of-the-art photonic performance.

Huntington’s disease cellular phenotypes are rescued non-cell autonomously by healthy cells in mosaic telencephalic organoids

Mosaic organoids where pathological and healthy cells are grown together, reveal the rescue of phenotypes in pathological cells due to communication with healthy cells without harming them, as demonstrated by single-cell RNA-sequencing data.

All-fiber frequency agile triple-frequency comb light source

The authors introduce an agile, all-fiber laser source with three frequency combs. Three EOM combs from a single laser are expanded in a tri-core nonlinear fiber, maintaining high mutual coherence. This system’s performance is showcased through a 2D four-wave mixing spectroscopy experiment.

Fibre multi-wave mixing combs reveal the broken symmetry of Fermi–Pasta–Ulam recurrence

The Fermi–Pasta–Ulam recurrence process—the recovery of the initial state of a nonlinear system after a certain time—is observed for the first time in a low-loss optical fibre by building a multi-channel, vector optical-time-domain reflectometer.

Phase-sensitive seeded modulation instability in passive fiber resonators

Modulation instability refers to the sensitivity of dispersive, weakly nonlinear systems to small perturbations and may be used as a source of optical gain. Here, the phase-sensitive properties of modulation instability with harmonic seeding in passive fiber resonators are investigated in theory and experiments.
