Programmable Integrated Photonics with Phase-Change Materials

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 Key Distribution with Integrated Photonics

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.
