Ultrasensitive displacement sensor based on photonic crystal fiber modal interferometer

Dash J.N.Jha R.Dass S.2025-02-172014https://idr.iitbbs.ac.in/handle/2008/533An ultrasensitive displacement sensor based on photonic crystal fiber modal interferometer using an external mirror is proposed. The mirror is displaced by a nano-positioner and the sensitivity of the sensor is 43 pm/nm. � 2014 OSA.enFiber optics sensorsInterferometryPhotonic crystal fiberUltrasensitive displacement sensor based on photonic crystal fiber modal interferometerConference Paper
