Development of Whispering Gallery Mode Polymeric Micro-optical Electric Field Sensors Tindaro Ioppolo1, Volkan Ötügen1, Ulas Ayaz1 1Mechanical Engineering Department, Southern Methodist University A high-sensitivity photonic micro sensor was developed for electric field detection. The sensor exploits the optical modes of a dielectric sphere. Changes in the external electric field perturb the sphere morphology leading to shifts in its optical modes. The electric field strength is measured by monitoring these optical shifts.
