Parametrically driven Kerr cavity solitons

Cavity solitons are optical pulses that propagate indefinitely in nonlinear resonators. They attracting attention, both for their many potential applications and connection to other fields of science. differ from laser dissipative they coherently driven. So far the focus has been on driving Kerr externally, at carrier frequency, which case a single stable localized solution exists fixed parameters. Here we experimentally demonstrate cavity twice using an all-fibre parametric oscillator. In configuration, called driving, two backgroundless opposite phase may coexist. We harness this multiplicity generate string random bits, thereby extending pool number generators Ising machines. Our results excellent agreement with seminal amplitude equation, highlighting connections hydrodynamic mechanical systems, among others.
