Dynamics of soliton pairs in a temporal cavity
Abstract:
We present a temporal cavity based on a time-lens in a temporal 2f degenerate cavity. This setup enables light to oscillate in the time domain, forming a temporal analog of an optical parametric oscillator (OPO). Our system offers high temporal resolution and sensitivity to ultrafast temporal and spectral changes. In our temporal OPO, we observe the formation of solitons under negative dispersion, which is opposed to typical Kerr solitons, due to the temporal Fourier transform of the time-lens. In addition, by exploiting our cavity sensitivity to ultrafast spectral and temporal changes, we detect novel temporal oscillations of soliton pairs caused by nonlinear polarization mode dispersion.
