Invention:
This technology is a step towards achieving time-varying photonics at optical (visible and IR) wavelengths. It functions by utilizing ultrashort pulses, shorter than ten femtoseconds, to modulate the reflectivity of a material at optical frequencies greater than 100 THz. The modulation rate can be tuned for different purposes, as both the pulse repetition rates and interpulse delay times are adjustable. This modulation creates an environment in which entangled proton pairs can be generated via the dynamic Casimir effect. Furthermore, the high temporal resolution and high repetition rate of this laser pulse method allows it to be applied to a broad range of time-varying photonic applications.
Background:
Developing time-varying photonics at optical wavelengths is a significant research challenge. To achieve time-varying photonics in the visible range, modulation of the optical properties of a material must be achieved at extremely high frequencies. For these reasons, the dynamic Casimir effect has never been observed at optical wavelengths. This invention bridges these gaps by leveraging high repetition rate laser pulses, offering a practical method to modulate optical properties at these frequencies. It takes advantage of the dynamic Casimir effect and serves as a source for entangled proton pairs and as a stepping stone for future advancement in the time varying photonics field. It paves the way for advanced applications in both quantum and time-varying photonic systems, providing a foundation for future innovations in optical technology.
