    A suite of flexible, integrated, high-index-contrast chalcogenide glass photonic devices, including waveguides, microdisk resonators, add–drop filters and photonic crystals, is reported. The devices are demonstrated to survive repeated bending to a submillimetre radius without any significant degradation in their optical performance.

    Two-, three- and higher multiphoton absorption processes are shown to occur in amyloid protein fibres, which are thought to play a role in various diseases, including Alzheimer's and Parkinson's diseases. The nonlinear optical behaviour of such proteins may also be useful for fabricating photonics devices.
