Abstract Glass is in general brittle and therefore usually cannot sustain large deformation. Recent advances in glass material development as well as micro‐mechanical designs, however, are set to defy the conventional wisdom through the demonstration of flexible integrated photonics that can be bent, twisted, and even stretched without compromising its structural integrity and optical performance. In this paper, we review the latest progress in this emerging field, and discuss the rational material and mechanical engineering principles underlying the extraordinary flexibility of these photonic structures. Leveraging these design strategies, we demonstrated bendable chalcogenide glass waveguide circuits, flexible glass waveguide‐integrated nanomembrane photodetectors, and stretchable glass photonics.
