"Silica microcavities and their novel technological oportunities in telecom and biosensing"

ntegrated photonic devices such as whispering gallery mode resonators have become a very interesting topic due to their ability to confine light for long periods of time in small mode volumes. These long photon lifetimes allow for circulating intensity to build up within the cavity, which opens up the possibility of accessing to multiple nonlinear optical effects; i.e., third order nonlinear optical phenomena. Recently, researchers along the world have taken advantage of this approach to fabricate functional tools such as lasers and frequency combs. Nanomaterials and organic compounds with unique optical properties represent a promising strategy to obtain more efficient nonlinear optical effects. Furthermore, these represent alternative strategies for reducing the threshold and increasing frequency comb span and insolate the nonlinear phenomena in microcavities. These approaches offer simple ways to decrease the power requirements needed to obtain wide-spanning frequency combs, opening the door to new applications beyond the laboratory through metallic nanoparticles, highly third-order nonlinear optical compounds and nanocrystals.
