Technology Description: The technique developed, uses the elasto-optic modulation to change the state of polarization (SOP) of the light. The output produced is sinusoidally varying in intensity. Using elasto-optic modulation and interferometric methods, measurements of birefringence can be made. Strain sensor using 2-mode PMF has been developed. The application areas are instrumentations, sensors, optics and photonics. The competitive advantages are: (i) Very high sensitivity compared to conventional sensors (ii) Cost effective and easy to fabricate.
