Title:
"In search of the ‘absolute’ optical phase"

Abstract:
Modelocked lasers have recently enabled access to a new parameter in ultrafast optics - the "absolute" phase. I'll discuss the properties of modelocked lasers that allow the "absolute" phase to be observed, the importance of this parameter, and one of several methods currently being pursued to measure and control it. This method involves quantum interference of injected photocurrents in semiconductors.
