We propose and demonstrate an all-optical wavelength routing approach that uses a tuning mechanism based upon the optical gradient force in a specially designed nano-optomechanical system. The resulting mechanically compliant 'spiderweb' resonator realizes seamless wavelength routing over a range of 3,000 times the intrinsic channel width, with a tuning efficiency of 309 GHz mW^(-1), a switching time of less than 200 ns, and 100% channel quality preservation over the entire tuning range. These results indicate the potential for radiation pressure actuated devices to be used in a variety of photonics applications, such as channel routing/switching, buffering, dispersion compensation, pulse trapping/release and widely tunable lasers.

Quantum matter built from nanoscopic lattices of atoms and photons (2018, background): “…the type of spin interaction (of exchange type) is fixed, as is the interaction range L for a given structure design, unless the structure itself exhibits some dynamic tunability [for example, via piezoeletric strain (Wong et al., 2004) or optomechanical forces (Rosenberg, Lin, and Painter, 2009)].”
Mechanical systems in the quantum regime (2011, background): “e spring constant of the resonator to kR = k0 − ∂Frad/∂u; the so-called optical spring [224, 225, 226, 227, 228, 39, 229, 230]. Similar to displacement-proportionalfeedback this can cool the resonator[39, 64, 231] and can even lead to bistability of the resonator position [225]. A much stronger cool”

Generalized non-reciprocity in an optomechanical circuit via synthetic magnetism and reservoir engineering (2016, background): “Optomechanical systems [14], involving the coupling of light intensity to mechanical motion via radiation pressure, are a particularly promising venue for studying synthetic fields, as they can be used to create the requisite large optical nonlinearities [15].”
