Abstract :
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. It has a switching contrast of 16 dB and a response time of 0.2 μs, which is 103 times faster than the traditional millimeter-scaled optical switches. It has potential applications in the high speed optical-packet-switching communications and the silicon-photonic integrated circuits.
