Abstract
Apparatus for providing a controllable signal delay along a transmission line, which apparatus comprises a transmission line conductor on a dielectric medium comprised wholly or partially or a semiconductor material, and adjacent periodically separated electromagnetically-coupled elements, the coupling between the elements and the transmission line conductor being controllable through photonic and/or electrical injection of electrical carriers into the dielectric medium, whereby the apparatus is such as to enable control of the velocity of electromagnetic propagation along the transmission line and thereby through the apparatus.
