Full C-band Tunable MEMS-VCSEL for Mobile Front- and Backhaul
In this paper we report on full C-band tunable, 10 Gbit/s capability, directly modulated micro-electromechanical system (MEMS) vertical-cavity surface-emitting laser (VCSEL) for next generation converged mobile fronthaul and backhaul applications, where the MEMS-VCSEL is used at the remote side of a wavelength routed WDM-PON system. To be compliant with the current ITU-T G.metro standardization...
متن کاملA MEMS Tunable Inductor
This paper reports a single-wafer micromachined radiofrequency (RF) inductor that can be integrated in a conventional RFIC device. The inductor achieved a quality factor greater than 9 at 5Ghz and a self-resonance frequency well above 15 GHz. The inductor is tunable and the inductance variation is greater than 8%.
متن کاملTunable Mems Capacitor For
We present the design of tunable capacitor based on MEMS simulated using COMSOL Multiphysics, which is an emerging engineering software environment used for modelling and simulation of any physical based structure. This model includes an electrostatic simulation for a given distance component in various microelectromechanical systems (MEMS) for electromagnetic fields in the radio frequency rang...
متن کاملShort-wavelength MEMS-tunable VCSELs.
We present electrically-injected MEMS-tunable vertical-cavity surface-emitting lasers with emission wavelengths below 800 nm. Operation in this wavelength range, near the oxygen A-band from 760-780 nm, is attractive for absorption-based optical gas sensing. These fully-monolithic devices are based on an oxide-aperture AlGaAs epitaxial structure and incorporate a suspended dielectric Bragg mirro...
متن کاملOptimization of electrically tunable VCSEL with intracavity nematic liquid crystal.
We optimize the wavelength tuning range of a Vertical-Cavity Surface-Emitting Laser with an intracavity layer of nematic Liquid Crystal (LC-VCSEL) lasing around 1.3 μm. The tunability is obtained by applying voltage to the liquid crystal layer, which esentially is to vary the refractive index from the extraordinary to the ordinary. We achieve 71.6 nm continuous tuning (without mode hopping) wit...
