Phase change materials (PCMs) are currently revolutionizing nanophotonics by providing ways to tune and reconfigure optical functionalities without any moving parts. Building on this phenomenon, the last decade has witnessed many exciting reports of novel devices exploiting PCMs such as for example beam-steering, tunable light emission, reflection and absorption, programmable metasurfaces and reconfigurable neural networks.

We present novel approaches for nonmagnetic optical isolation that combine efficient acousto-optic scattering processes and dispersion engineering to create nonmagnetic optical isolators with wide (> 1 THz) optical bandwidth. We employ complementary approaches for isolation based on acousto-optic strong coupling and nonreciprocal interference.

Phase-change materials (PCMs) have emerged as a promising platform to modulate light in a nonvolatile manner—a reversible switching between their stable amorphous and crystalline states leads to an impressive refractive index contrast (∆n, ∆k ~1−3). The last decade has seen a growing interest in such a combination of properties for a variety of nonvolatile programmable devices, such as metasurfaces, tunable filters, phase/amplitude modulators, color pixels, thermal camouflage, photonic memories/computing, plasmonics, etc.

Quantum computing’s rapid advancement threatens current cryptography, which relies on complex problems solvable by quantum computers. This necessitates the development of “quantum-safe” technologies for future network protection. Today’s data is also at risk from “harvest now, decrypt later” attacks, where encrypted messages are stored for decryption once quantum processors are available. This is especially concerning for long-term valuable information like financial records and medical data.
