Investigations towards the development of a novel multimodal fibre optic sensor for oil and gas applications.
… earth, causing serious safety concerns. Hence, sensing of critical multiple parameters like high pressure, high temperature (HPHT), chemicals, etc., are required at longer distances. Traditional electrical sensors operate less effectively under these extreme environmental conditions and are …

Writing and characterisation methods for UV-photosensitivity based devices and their applications
… integrated optical devices for telecoms and sensing applications. One major scope is the improvement of grating fabrication specifications by introducing new writing techniques and the use of advanced characterisation methods for grating testing. For the first time the polarisation control …

Development of Fiber Optic Sensors using Femtosecond Laser for Refractive Index and Temperature Measurements
… written by ultrashort pulses. Laser writing parameters (such as beam diameter, pulse energy, scanning speed, depth of focus, etc.) are then further tuned to write pulse filamentation induced refractive index change in optical fibers suitable for fiber grating fabrication. In order to design …
