Abstract
Sb2S3 is currently being developed for programmable photonics applications. It is particularly appealing because it has a relatively large bandgap of 2.05 eV in the amorphous state, which means that it is transparent in the visible spectrum. Moreover, the phase change invokes a large change in refractive index, which means that it can be used to tune photonic resonators. We have used this effect to demonstrate programmable couplers, nano resonator display pixels, and beam steering metasurfaces. In this talk I will discuss these works, and then the challenges and opportunities for Sb2S3 photonics. I will also discuss how it has the potential to revolutionise the fields of communication, information, and health.
