Vukovic, Natasha, Healy, Noel, Mehta, Priyanth, Day, Todd D., Sazio, Pier-John, Badding, John V. and Peacock, Anna C. (2012) Thermal nonlinearity in silicon microcylindrical resonators. Applied Physics Letters, 100, (18), 181101-[4 pages]. (doi:10.1063/1.4709424).
We explore the thermally induced nonlinearity in hydrogenated amorphous silicon microcylindrical resonators that are fabricated from the silicon optical fiber platform. In particular, we use a pump-probe technique to experimentally demonstrate thermally induced optical modulation and determine the response time. Through characterization of the thermal properties and the associated resonance wavelength shifts we will show that it is possible to infer the material absorption coefficient for a range of whispering gallery mode resonators.
