We develop a miniaturized electrostatically tunable optomechanical oscillator, whose frequencies can be electrostatically tuned by as much as 10%. By taking advantage of the optical and the electrical spring, the oscillator achieves a high tuning sensitivity without resorting to mechanical tension. Particularly, the high-Q optical cavity greatly enhances the system sensitivity, making it extremely...
In this paper, a Nano-opto-mechanical (NOM) switch is designed, simulated and experimentally demonstrated, using the electromagnetically induced transparency (EIT)-like effects of coupled-ring resonator. The control of the switch is realized by optical force between the silicon waveguide and the dielectric substrate. As the injection pump power increases from 0 to 6 mW, the normalized power of transmission...
This paper presents a digital mirror for tunable laser wavelength selection using microelectromechanical systems (MEMS) technology. The digital mirror which has discrete reflection spectrum is totally different compared to the current broadband mirrors MEMS tunable lasers . The reflection of the digital mirror can be tuned by digital pumping signals which promise fast output wavelength switching....
