An integrated photonic Mach-Zehnder interferometer with no electrodes for sensing electric fields
A new configuration for a Mach-Zehnder interferometric electric field sensor device utilizing the electrooptic effect is reported. The lithium niobate device uses no metallic electrodes and operatesExpand
Method of phase-modulating signals in optical fibres: application to optical-telemetry systems
By attaching a piezoelectric transducer that modulates the mechanical tension over a short section of fibre, signals in optical fibres are phase modulated. The technique is applicable to a I-wayExpand
Advanced materials and device technology for photonic electric field sensors
Photonic methods for electric field sensing have been demonstrated across the electromagnetic spectrum from near-DC to millimeter waves, and at field strengths from microvolts-per-meter toExpand
OFDR Diagnostics For Fiber/Integrated Optic Systems And High Resolution Distributed Fiber Optic Sensing
Optical frequency domain reflectometry (OFDR) shows promise as a diagnostic tool for high resolution ranging in fiber optic networks/integrated optic devices, and for high resolution distributedExpand
Optical SETI observatories in the new millennium: a review
The Optical Search for Extraterrestrial Intelligence is now 40 years old. However, it was only during the closing years of the 20th Century, after a 25-year hiatus, that the optical search hasExpand
