This paper reports a NEMS integrated photonic system, which integrate tunable laser, optical cross correct and variable optical attenuators. The NEMS integrated photonic system is fabricated with nano-silicon-photonic fabrication technology to integrate various functions in a single silicon photonic circuit chip. The high light-confinement capability of the nano-silicon waveguides guarantees superior...
The paper presents a monolithically integrated tunable laser with loop-back external cavity tunable based on double ring resonators. It consists of a gain chip and a double ring resonator structure in a loop-back external cavity, made of silicon photonic waveguides. In the experiment, it measures 40-nm wavelength tuning, > 40 dB side mode suppression ratio (SMSR) and the average output power is...
A tunable laser based on double-ring external resonant cavity is designed, fabricated and tested. The double-ring resonator external cavity consists of a silicon waveguide ring resonator, a p-i-n doped silicon ring resonator, and a superluminescent diode (SLED). The laser is fabricated on a SOI wafer and the wavelength is tuned by injecting electrical currents to p-i-n structures. In the experiment,...
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....
This paper reports a theoretical and experimental study of a MEMS injection-locked laser (ILL). The micromachined injection-locked laser consists of a MEMS tunable laser (master) and a Fabry-Perot multimode laser (slave) that is integrated by using deep RIE processes onto a single chip. Based on the experimental results, hysteresis property in asymmetrical tuning curve is observed and optical bistability...
