This paper presents an optical force driven nano-machined actuator and the “pull-back” effect of a free-standing arc in an opto-mechanical ring resonator system. This nano-actuator obtains a maximal central displacement of 43.1 nm, with an actuation resolution of 0.28 nm, via tuning the wavelength of the control light at a fixed optical power of 2.8 mW. The “pull-back” effect occurs at the maximal...
Microparticle trapping and manipulation using the optical force in double coupled ring resonator (DCRR) through wavelength tuning is reported in this paper. The DCRR consists of two coupled identical rings, and a waveguide that is side-coupled to the two rings. The microparticles are propelled by optical radiation force and trapped by optical gradient force, which are both generated by the evanescent...
In this paper, an optical switch driven by the optical force is demonstrated based on Nanoelectromechanical system (NEMS) technology. The switch consists of a Mach-Zehnder interferometer (MZI) and a ring resonator. One of the MZI arms is suspended to enable optical switching by optical force induced displacement. The optical force is introduced by injecting a control light into the ring resonator...
