“…Two resonances overlap and interact strongly for |ε|/κ 1. For ε = 0 and H + = H − , the model becomes symmetric and, therefore, its symmetric solution (see the black lines in the ε = 0 panels of Figure 2a) goes through the symmetry breaking bifurcation [5,6,15].…”

“…Around and substantially beyond this range, the soliton pulses in the plus-field are not able to exist simply because the system does not offer a low-amplitude background state for the bright soliton to nest on (see the grey stripe in Figure 2b and the respective no-soliton range in Figure 2c). This is the essence of the soliton-blockade effect, when the solitons can be switched on and off by tuning the frequency of the counter-propagating field, so that ε is tuned within the soliton-forbidden interval [15]. Figure 3 shows how the soliton-blockade domains are shaped in the (δ 0 , ε) and (H − , ε) parameter spaces, respectively.…”

“…The deeper insight into the independence of the XPM nonlinearity from the phase relations between the interacting modes [12][13][14] has recently led us to the prediction of the soliton-blockade effect [15]. The blockade is achieved when the tuning frequency of one of the counter-rotating fields first disrupts and then restores the soliton transmission in the other field.…”

Considering a bidirectionally pumped ring microresonator, we provide a concise derivation of the model equations allowing us to eliminate the repetition rate terms and reduce the nonlinear interaction between the counter-propagating waves to the power-dependent shifts of the resonance frequencies. We present the simulation results of the soliton control by swiping the frequency of the counter-propagating wave in the forward and backward directions and with the soliton-blockade effect either present or not. We highlight the non-reciprocity of the forward and backward scans. Furthermore, we report the soliton crystals and breathers existing in the vicinity of the blockade interval.

We show that nonreciprocal optical solitons that are immune to backscattering-induced losses appear in a spinning optical Kerr resonator. Nonreciprocity in this device results from the Sagnac-Fiezau drag effect, which is different for pump fields propagating in the spinning direction or in the direction opposite to it. We find that these nonreciprocal solitons are more robust against backscattering losses if the spinning speed of the resonator is properly set. Our work represents a stable nonreciprocal soliton device and provides a promising technique for one-way soliton isolators and lasers, backaction-immmune soliton communication, and enhanced soliton-comb metrology.

Dispersion engineering of microring resonators is crucial for optical frequency comb applications, to achieve targeted bandwidths and powers of individual comb teeth. However, conventional microrings only present two geometric degrees of freedom – width and thickness – which limits the degree to which dispersion can be controlled. We present a technique where we tune individual resonance frequencies for arbitrary dispersion tailoring. Using a photonic crystal microring resonator that induces coupling to both directions of propagation within the ring, we investigate an intuitive design based on Fourier synthesis. Here, the desired photonic crystal spatial profile is obtained through a Fourier relationship with the targeted modal frequency shifts, where each modal shift is determined based on the corresponding effective index modulation of the ring. Experimentally, we demonstrate several distinct dispersion profiles over dozens of modes in transverse magnetic polarization. In contrast, we find that the transverse electric polarization requires a more advanced model that accounts for the discontinuity of the field at the modulated interface. Finally, we present simulations showing arbitrary frequency comb spectral envelope tailoring using our Fourier synthesis approach.
