Title:
METHODS AND DEVICES FOR GENERATING BIPOLAR SIGNALS FROM UNIPOLAR SIGNALS
Document Type and Number:
WIPO Patent Application WO/2012/162702
Kind Code:
A3
Abstract:
Methods, circuits and systems are provides to produce a bipolar signal across a load from two or more unipolar signals. In a circuit that includes a first and a second energy source, as well as a first and a second photonic switch, a first unipolar signal is generated from a first current flow across the load upon activation of the first switch. A second unipolar signal is generated from a second current flow across the load upon activation of the second switch. The bipolar signal with any desired spectral and amplitude characteristics is produced across the load by controlling the relative delay between the activation of the first and second photonic switches. Spectral content and shape of the bipolar signal can be adjusted by controlling the current flows from the one or more energy sources through, for example, modulation of the optical beams incident on the photonic switches.
