Abstract: A system for dispersion compensation in a terahertz system includes an optical fiber configured to transmit an optical pulse, a compensator optically coupled to the optical fiber, the compensator configured to compensate for a dispersion of the optical pulse caused as the optical pulse propagates through the optical fiber, and an optically induced terahertz device optically coupled to the compensator, whereby the optically induced terahertz device is configured to transmit or receive terahertz radiation.

Abstract: An optical delay line device includes a rotatable wheel and one or more prisms mounted about the circumference of the wheel. The one are more prisms are positioned to retroreflect the optical beam that passes approximately tangent to the wheel to cause a delay or phase shift to the beam as the wheel rotates.
