This mechanical vibration can be thought of as a musical note from a tuning fork, but
in optomechanics it involves tiny devices specifically designed for this purpose.
According to Konstantin Bliokh, the corresponding author of the paper, «Our findings revisit fundamental momentum properties of light and, revealing a new type of optical force,
enrich optomechanics.»
In their studies, Bahl's research group uses the extremely minute forces exerted by light to generate and control mechanical vibrations of microscale and nanoscale devices — a field
called optomechanics.
By confining various liquids inside a hollow microfluidic optomechanical (μFOM) resonator, researchers built the first - ever bridge
between optomechanics and microfluidics.
«These mechanical vibrations can, in turn, «talk» to liquids within the hollow device and provide optical readout of the mechanical properties,» said Bahl, who is first author of the paper, «Brillouin
cavity optomechanics with microfluidic devices,» published this week in Nature Communications.
The experimental design draws from his recent research in the field
of optomechanics, which Savona describes as «the art of conceiving systems in which light interacts, in highly controlled and highly tailored way, with a mechanical vibration of some sort.»
Martin did his PhD at the University of Queensland, Australia and a postdoc at Heriot - Watt University in Scotland, working on photonic quantum information processing, quantum foundations, and
optomechanics.
