Description
The temporal degree of freedom of photons is a powerful resource for encoding and transmitting information across a broad range of applications, including high-speed optical telecommunications, light-based diagnostics, remote sensing, and spectroscopy, in both classical and quantum domains. To harness the full potential of this temporal dimension, we require methods capable of user-defined manipulation of photonic temporal profiles, operating at light-speed and with high energy efficiency.
This talk will present an overview of temporal optics for information processing, with a particular focus on a universal framework known as energy-redistribution photonic processing. Based on energy-preserving phase-only linear manipulations, this framework enables highly efficient, customized control of the temporal structure of light. As such, it supports a wide variety of functions for both classical and quantum light, such as time/frequency scaling, passive amplification, lossless logic operations, and joint time-frequency analysis. Notably, this approach can be practically implemented using widely available fiber-optics and integrated photonic devices.
We will illustrate the core principles of this framework through a methodology specifically designed to recover photonic information severely degraded by noise, a problem of broad fundamental and practical importance. Particular emphasis will be placed on the denoising and regeneration of time-energy entangled states through passive coherent energy enhancement, representing a key enabling capability for future quantum communication, sensing, and computing technologies.
