Electrically tunable hot-silicon terahertz attenuator
We have developed a continuously tunable, broadband terahertz attenuator with a transmission tuning range greater than 10. Attenuation tuning is achieved electrically, by simply changing the DC voltage applied to a heating wire attached to a bulk silicon wafer, which controls its temperature between room temperature and !550 K, with the corresponding free-carrier density adjusted between !10 cm...
متن کاملElectrically tunable porous silicon active mirrors
We demonstrate tunable mirrors that consist of a porous silicon microcavity infiltrated with liquid crystal molecules. We show theoretically that by utilizing the electro-optic properties of liquid crystals and the sensitivity of the microcavity resonance position to small changes in optical thickness, the porous silicon active mirror can be switched on (high reflectance) and off (low reflectan...
متن کاملA new class of electrically tunable metamaterial terahertz modulators.
Switchable metamaterials offer unique solutions for efficiently manipulating electromagnetic waves, particularly for terahertz waves, which has been difficult since naturally occurring materials rarely respond to terahertz frequencies controllably. However, few terahertz modulators demonstrated to date exhibit simultaneously low attenuation and high modulation depth. In this letter we propose a...
متن کاملElectrically tunable solid-state silicon nanopore ion filter
We show that a nanopore in a silicon membrane connected to a voltage source can be used as an electrically tunable ion filter. By applying a voltage between the heavily doped semiconductor and the electrolyte, it is possible to invert the ion population inside the nanopore and vary the conductance for both cations and anions in order to achieve selective conduction of ions even in the presence ...
متن کاملElectrically driven motion of micro-fluids in air-silica microstructure fiber: application to tunable filter/attenuator
We present an approach for manipulating light in an optical fiber where efficient modal field interaction is achieved between modes propagating in an air-silica microstructure optical fiber and micro-fluids incorporated in the air-holes of the fiber. We demonstrate this apporach in terms of applications to tunable devices.
