Title :

Non-Linear Optical Organic Micro-Resonators


Bottom-up molecular self-assembly technique has emerged as one of the powerful methods to produce miniaturized organic photonic structures, such as optical waveguides, lasers, resonators, filters, circuits and modulators.  Optical waveguides and modulators are used to control the light propagation down to microscale and modulate the light propagation speed, respectively. In optical resonators their mirror-like geometry allows them to tightly trap the photons by repeated total internal reflection at the air-matter interface and act as optical gain media exhibiting high-quality factor (Q) with the low optical loss. We have been performing single-particle micro-PL spectroscopy studies to exploit the geometrical features of diverse self-assembled organic structures for photonic applications. In my talk, I will discuss some original results achieved in our group in linear and non-linear optical organic optical waveguide and microresonators useful for signal enhancement, sensing and lasing applications. I will also discuss our attempts towards creation and study of photonic molecules.
