• Dynamics of soliton pairs in a temporal cavity

  Optics Express · 2026-03-27

  articleOpen access1st authorCorresponding

  We present a temporal cavity based on a time-lens in a temporal 2 f 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.

  We present a temporal cavity based on a time-lens in a temporal 2f configuration. This setup enables light to oscillate in the time domain, forming a temporal analogue 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, and study the temporal dynamics of such solitons. In addition, by exploiting our cavity sensitivity to ultrafast spectral and temporal changes, we can detect novel temporal oscillations of soliton pairs caused by nonlinear polarization mode dispersion.

• High-order autocorrelation by a cascade time-lens

  Optics Letters · 2025-06-23 · 1 citations

  article

  High-order temporal autocorrelation functions provide critical insight into the structure and phase of ultrafast signals and are essential in fields ranging from optics to signal processing. In this work, we present a single-shot method for measuring high-order temporal autocorrelation using a cascade time-lens system based on four-wave mixing. We derive the imaging conditions for each cascade order, demonstrating that the system functions as distinct temporal imaging systems, simultaneously, each deriving a different correlation order. Numerical simulations confirm that the cascade outputs represent time-reversed images and high-order temporal autocorrelations of the input signal. Experimental results using double-pulsed input validate our model, showing reconstruction of the high-order temporal autocorrelation. This system enables high-resolution temporal characterization with a single nonlinear component and has applications in ultrafast analysis and optical communication.

• Aharonov-Bohm effect in the time domain

  Physical Review Research · 2025-06-05 · 2 citations

  articleOpen access

  In the Aharonov-Bohm effect, charged particles accumulate a phase as they travel in space, encircling a source of magnetic flux. We develop a temporal analog of the Aharonov-Bohm effect, where the photons' path is in the time-domain instead of the spatial domain, and moreover demonstrate it experimentally with entangled photon pairs rather than single, uncorrelated quanta. Relying on the temporal SU(1,1) interferometer, the constructed interferometric scheme excels in its temporal resolution and sensitivity. This system can be applied for quantum-enhanced measurements, metrology at GHz frequencies, advanced sensing of dispersion properties, and high-precision temporal measurements.
