Several kinds of nonlinear optical effects have been observed in recent years using silicon waveguides, and their device applications are attracting considerable attention. In this review, we provide a unified theoretical platform that not only can be used for understanding the underlying physics but should also provide guidance toward new and useful(More)
We measure the transmission of THz pulses through thin films of YBa 2 Cu 3 O 7−δ at temperatures between 10 K and 300 K. The pulses possess a usable bandwidth extending from ∼0.1 – 1.5 THz (3.3 cm −1 – 50 cm −1). Below T c we observe pulse reshaping caused by the kinetic inductance of the superconducting charge carriers. From transmission data, we extract(More)
