WebOptical sampling by cavity tuning (OSCAT) enables cost-effective realization of fast tunable optical delay using a single femtosecond laser. We report here a dynamic model of OSCAT, taking into account the continuous modulation of laser repetition rates. This allows us to evaluate the delay scan depth under high interferometer imbalance and high scan rates, … WebApr 9, 2024 · It takes into consideration the physical requirements underlying the phase and unity amplitude modulation of the cavity resonance, that is, a unity reflectivity for the lower interface and a relatively sufficient high-Q resonance such that full phase modulation can be experienced using the thermo-optical effect in silicon (Si) nano-ridges. WebDec 29, 2016 · The most used techniques for THz detection is to utilize short laser pulses in the order of 100fs to take a snapshot of your electrical field strength at a defined time after creation of the THz pulse. As the THz creation and detection pulses are coming from the same cavity, they are phase locked. granddad\u0027s apple orchard hendersonville nc
