This paper presents a compact silicon-photonic based optical cross connect (OXC) driven by the optical gradient force. Each switch element consists of a waveguide-crossing-coupled micro-ring resonator and a suspended arc. The device is fabricated with a standard CMOS compatible process using deep-UV 248-nm lithography with a double-etch technique. A switching time of 0.24 µs is experimentally demonstrated...
This paper reports a Nanoelectromechanical System (NEMS) Variable Optical Attenuator (VOA) driven by the optical gradient force. The VOA is realized via a waveguide based directional coupler. The gap in the directional coupler is controlled via an optical force driven actuator. The doubly-clamped silicon beam actuator is controlled by tuning the wavelength of control light. The signal light can be...
