Area of Science:

  • Optics and Photonics
  • Ultrafast Science
  • Materials Science

Background:

  • Optical time-refraction is a phenomenon where the temporal properties of light change due to rapid variations in the refractive index of a medium.
  • Previous studies have explored time-refraction, but experimental investigations at the single optical cycle timescale are challenging.
  • Epsilon-near-zero (ENZ) materials offer unique optical properties due to their near-zero permittivity, making them promising for manipulating light.

Purpose of the Study:

  • To experimentally investigate optical time-refraction phenomena occurring at extremely short timescales, specifically down to a single optical cycle.
  • To study the spectral dynamics of probe pulses propagating through materials with abrupt refractive index changes induced by modulator pulses.
  • To explore the potential of ENZ materials for generating and controlling ultrafast optical effects.

Main Methods:

  • An experimental setup was designed to study the propagation of a probe optical pulse through a sample.
  • A strong modulator pulse was used to induce a rapid and significant change in the refractive index of the sample.
  • The spectral response of the probe pulse was analyzed to observe red-shifting and blue-shifting phenomena associated with time-refraction.

Main Results:

  • Optical time-refraction was successfully observed in the single optical cycle regime.
  • A red-shift in the probe pulse spectrum was observed upon increasing the refractive index, followed by a blue-shift upon relaxation.
  • The rise time of the spectral shift was found to be proportionally shorter when the temporal width of the modulator pulse was reduced to approximately 5-6 femtoseconds.

Conclusions:

  • The experiments confirm the occurrence of optical time-refraction at single optical cycle timescales.
  • The findings highlight the relationship between modulator pulse width and the temporal dynamics of spectral shifts.
  • These results open avenues for exploring fundamental physics in ultrashort time frames and developing photonic time-crystals.
