Time Crystals in Actively Mode-locked Lasers
Ruiling Weng, Elias R. Koch, Jesús Yelo-Sarrión +4
We report the first experimental observation of discrete time-crystal phases and crystallites in an actively mode-locked semiconductor laser. By tuning either the bias current or t…
Strongly resonant polarization dynamics of pulse trains in a spin-flip model for an excitable microlaser with delayed self-feedback
Stefan Ruschel, Sylvain Barbay, Neil G. R. Broderick +1
Motivated by recent experimental observations concerning the polarization dynamics in an excitable microlaser with saturable absorber coupled to an external feedback mirror reporte…
Density-encoded line integral convolution: polarisation optical axis tractography using centroidal Voronoi tessellation
Darven Murali Tharan, Marco Bonesi, Daniel Everett +4
Visualising complex polarimetry optical axis fields is challenging. We introduce density-encoded line integral convolution (DELIC), a novel approach that builds on the classic line…
Depth-resolved polarisation sensitive optical coherence tomography reveals the complex microanatomical response of cartilage to compression
Darven Murali Tharan, Marco Bonesi, Daniel Everett +5
Conventional methods for analysing cartilage microstructure under mechanical loading are largely destructive. In this work, we evaluate the efficacy of using depth-resolved polaris…
Regenerative vectorial breathers in a delay-coupled neuromorphic microlaser with integrated saturable absorber
Stefan Ruschel, Venkata A. Pammi, Rémy Braive +5
We report on the polarization dynamics of regenerative light pulses in a micropillar laser with integrated saturable absorber coupled to an external feedback mirror. The delayed se…
On-Chip Parametric Synchronization of a Dissipative Kerr Soliton Microcomb
Gregory Moille, Pradyoth Shandilya, Miro Erkintalo +2
Synchronization of oscillators is ubiquitous in nature. Often, the synchronized oscillators couple directly, yet in some cases synchronization can arise from their parametric inter…
