Abstract

Over the past decade or so there has been growing interest in optomechanical interactions, particularly in connection with laser cooling [1]. Optomechanical nonlinearities have also been studied in mechanically compliant dual-nanoweb fibres, where radiation forces cause glass membranes to flex, changing the optical properties of the system [2]. The original laser-based optomechanical system – optical tweezers – was however studied in the 1970s by Ashkin [3]. A recent example is the propulsion of particles in hollow-core photonic crystal fibre (HC-PCF) [4, 5].
