  • We fabricate optical fiber with the same dimensions as standard communication single mode fiber (SMF) with the glass core surrounded by 40 to 60 nm thick lithium niobate (LiNbO3) film as schematically shown in Fig 1. Lithium Niobate Cylinder Fiber (LNCF) can be used as strain sensor and sonar detector. We use the LNCF in a mode where the strain causes a change in the light propagating through the fiber.
