Abstract
We have developed optical fibers with a thin approximately 40 to 60 nm thick Lithium Niobáte Layer at the glass core and cladding boundary. These Lithium Niobate Cylinder Fibers (LNCF) are now in the process of being commercialized as strain gauges for bridges, tunnels, pipe lines and aircraft components. An application as a sonar sensor is also being investigated. LNCF strain sensors use light amplitude detection rather man phase detection. Amplitude detection is easier to implement and is substantially less costly. LNCF's when used as light amplitude sensing sonar detectors are over 1000 times more sensitive man standard Single Mode Fibers. LNCFs use so called "Non Propagating" light modes rather than the conventional propagating modes.
