“…This type of behaviour provides an alternative way to obtain self-switching between dominant and suppressed fields in polarisation or counter-propagating systems, as discussed by refs. 11,12 . In these studies the "periodic selfswitching"-regions were extremely narrow, while here we observe very broad regions where periodic self-switching behaviour is possible.…”

“…In the first example, two, otherwise identical, input beams enter the resonator in opposite directions. The evolutions of these field, including their SSB, have been studied extensively theoretically [6][7][8][9][10][11][12][13] , and, more recently, experimentally [14][15][16][17][18] . The second example involves a single, linearly polarised, laser input splitting into two orthogonally polarised components.…”

Multi-stage spontaneous symmetry breaking of light in Kerr ring resonators

Symmetry breaking of light states is of interest for the understanding of nonlinear optics, photonic circuits, telecom applications and optical pulse generation. Here we demonstrate multi-stage symmetry breaking of the resonances of ring resonators with Kerr nonlinearity. This multi-stage symmetry breaking naturally occurs in a resonator with bidirectionally propagating light with orthogonal polarization components. The derived model used to theoretically describe the system shows that the four circulating field components can display full symmetry, full asymmetry, and multiple versions of partial symmetry, and are later shown to result in complex oscillatory dynamics - such as four-field self-switching, and unusual pulsing with extended delays between subsequent peaks. To highlight a few examples, our work has application in the development of photonic devices like isolators and circulators, logic gates, and random numbers generators, and could also be used for optical-sensors, e.g. by further enhancing the Sagnac effect.

“…The first symmetry breaking principle is due to the counter-propagation of two input beams in opposite directions, which are otherwise identical. The evolutions of counter-propagating fields circulating ring resonators, including their SSB, have been studied extensively theoretically [5][6][7][8][9][10][11], and, more recently, experimentally [12][13][14]. The second symmetry breaking principle that is important for our discussions is that of a single, linearly polarised, laser input splitting into two orthogonally polarised components.…”

Symmetry breaking of light states is of interest for the understanding of nonlinear optics, photonic circuits, telecom applications and optical pulse generation. Here we demonstrate 4-fold symmetry breaking of the resonances of ring resonators with Kerr nonlinearity. This symmetry breaking naturally occurs in a resonator with bidirectionally propagating light with orthogonal polarization components. The four circulating field components are shown to exhibit multiple and, nested and isolated, spontaneous symmetry breaking bifurcations, and are also capable of complex oscillatory dynamics -such as four-field self-switching, and unusual temporal cavity soliton-like dynamics on time scales of multiple round-trip times, with extended delays between subsequent generations.

Complex Optical Switching in a Ring Resonator with Counter Propagating Light

Abstract: We show that regular and complex self-switching oscillations arise in a ring resonator with balanced bi-directional pumping, when two asymmetric attractors merge. Our results provides a road map of optical switching for experimental studies.
