Query: Near-field tuning of optomechanical coupling in a split-beam nanocavity   Tunable evanescent coupling is used to modify the optomechanical interactions
within a split-beam photonic crystal nanocavity. An optical fiber taper probe
is used to renormalize the optical nanocavity field and introduce a dissipative
optomechanical coupling channel, reconfiguring and enhancing coupling between
the optical and mechanical resonances of the device. Positioning of the fiber
taper allows preferential coupling to specific mechanical modes and provides a
mechanism for tuning the optomechanical interaction between dissipative and
dispersive coupling regimes.
