The unique optical properties of phase change materials (PCMs) can be exploited to develop efficient reconfigurable photonic devices. Here, we design, model, and compare the performance of programmable 1 × 2 optical couplers based on: Ge2Sb2Te5, Ge2Sb2Se4Te1, Sb2Se3, and Sb2S3 PCMs. Once programmed, these devices are passive, which can reduce the overall energy consumed compared to thermo-optic or electro-optic reconfigurable devices. Of all the PCMs studied, our ellipsometry refractive index…

A New Family of Ultralow Loss Reversible Phase‐Change Materials for Photonic Integrated Circuits: Sb2S3 and Sb2Se3
Phase‐change materials (PCMs) are seeing tremendous interest for their use in reconfigurable photonic devices; however, the most common PCMs exhibit a large absorption loss in one or both states.

Nonvolatile programmable silicon photonics using an ultralow-loss Sb2Se3 phase change material
TLDR
To demonstrate full control over the flow of light, nanophotonic digital patterning is introduced as a previously unexplored conceptual approach with a footprint orders of magnitude smaller than state-of-the-art interferometer meshes, which enables a wealth of possibilities in high-density reconfiguration of optical functionalities on silicon chip.

Plasmonic monolithic lithium niobate directional coupler switches
TLDR
Plasmonic electro-optic directional coupler switches consisting of two closely spaced nm-thin gold nanostripes on LN substrates that guide both coupled electromagnetic modes and electrical signals that control their coupling are demonstrated, thereby enabling ultra-compact switching and modulation functionalities.
Time-domain separation of optical properties from structural transitions in resonantly bonded materials.
TLDR
The connection between optical properties and structure can be broken using a combination of single-shot femtosecond electron diffraction and optical spectroscopy to follow the lattice dynamics and dielectric function in the phase-change material Ge2Sb2Te5 during an irreversible state transformation.
Phase Change Material Photonics
TLDR
This review will discuss how to design tuneable-MDM photonics devices, their advantages, and their limitations, before concentrating on PCM-tuned Metal-Dielectric-Metal (MDM) structures.
