Abstract
Controlling the flow of photons is crucial for advancing quantum
technologies. We introduce the concept of spatiotemporal photon blockade for
nonreciprocal quantum absorption, utilizing space-time-periodic metasurfaces.
Our study presents a methodology for experimentally realizing this effect,
where photon frequency coherence with the metasurface's space-time modulation
enables one-way quantum absorption. In this system, forward-traveling photons
are energetically modulated and absorbed within the slab, while
backward-traveling photons are transmitted without interaction. Our analysis
includes band structure, isofrequency diagrams, and nonreciprocal absorption
results. These findings lay the groundwork for developing nonreciprocal quantum
devices and enhancing photon management in milli-Kelvin temperature quantum
systems.
