Research Proposal Lexicon

Silicon Germanium – A material used in semiconductors to allow for low current and high frequency performance.

Silicon Micro-Ring Resonator – The basic unit of the photonic circuit. When the voltage across a  micro-ring resonator is positive, the resonant frequency of the micro-ring changes such that it resonates with the incoming light source and allows photons to pass through it.

Electro-Optic Modulation: The method in which the resonant wavelength of the micro-ring resonators is changed. In our case, this is achieved by applying a voltage across the micro-ring resonator.

Quality Factor: A measure of how underdamped an oscillator or resonator is – higher Q, lower rate of energy loss

Decibel – A logarithmic unit to express a ratio of two physical quantities. In this case,

SOI – silicon on insulator – A technology used in microelectronics to reduce parasitic device capacitance

Optical Wave Guide – A transparent tube usually made with a polymer with a high refractive index. This allows light entering the tube to travel and bend along its length and exit out the other end.

GPU – Graphical Processing Unit. This is the component responsible for generating the pixel data for computer screens.

CMOS – Complementary Metal Oxide Semiconductor. A technology used to construct basic elements inside of an integrated circuit, such as transistors or diodes.

Attenuation – The amount by which a signal loses its original power when traveling through some medium.

Photonics – An area of science that deals with the generation, manipulation, and detection of light.
