| Abstract: | A nano-optomechanical transducer provides ultrabroadband coherent
optomechanical transduction based on Mach-wave emission that uses
enhanced photon-phonon coupling efficiencies by low impedance effective
phononic medium, both electrostriction and radiation pressure to boost
and tailor optomechanical forces, and highly dispersive electromagnetic
modes that amplify both electrostriction and radiation pressure. The
optomechanical transducer provides a large operating bandwidth and high
efficiency while simultaneously having a small size and minimal power
consumption, enabling a host of transformative phonon and signal
processing capabilities. These capabilities include optomechanical
transduction via pulsed phonon emission and up-conversion, broadband
stimulated phonon emission and amplification, picosecond pulsed phonon
lasers, broadband phononic modulators, and ultrahigh bandwidth true time
delay and signal processing technologies. |
