Nanomechanical Optical Fiber with Embedded Electrodes Actuated by Joule Heating

Nanomechanical Optical Fiber with Embedded Electrodes Actuated by Joule Heating

Nanomechanical optical fibers with metal electrodes embedded in the jacket were fabricated by a multi-material co-draw technique. At the center of the fibers, two glass cores suspended by thin membranes and surrounded by air form a directional coupler that is highly temperature-dependent. We demonstrate optical switching between the two fiber cores by Joule heating of the electrodes with as lit...

Picosecond Joule heating in photoconductive switch electrodes

Nanomechanical optical fiber.

Optical fibers are an excellent transmission medium for light and underpin the infrastructure of the Internet, but generally after fabrication their optical properties cannot be easily modified. Here, we explore the concept of nanomechanical optical fibers where, in addition to the fiber transmission capability, the internal core structure of the fiber can also be controlled through sub-micron ...

Remote Joule heating by a carbon nanotube.

Minimizing Joule heating remains an important goal in the design of electronic devices. The prevailing model of Joule heating relies on a simple semiclassical picture in which electrons collide with the atoms of a conductor, generating heat locally and only in regions of non-zero current density, and this model has been supported by most experiments. Recently, however, it has been predicted tha...

Polycrystalline Silicon Produced by Joule-Heating Induced Crystallization

An electric field was applied to a conductive layer to induce Joule heating in order to generate the intense heat needed to carry out the crystallization of amorphous silicon. Complete crystallization was observed via Joule heating under typical processing conditions. Crystallization was accomplished throughout the sample within the range of microseconds of the heating, thus demonstrating the p...
