Just like chemical reagents are used for testing, chemically transforming, and sensing other compounds, photons could serve the same purpose. The key challenge is determining how to practically create ‘photonic reagents’ that have the desired selectivity. Success in this endeavor can result in numerous significant applications, for example non-invasive cancer detection, advanced proteomic analysis capable of detecting weakly bound post-translational modification, and non-intrusive explosives trace detection. The approach followed by the Dantus Research Group involves the use of ultrashort femtosecond laser pulses with phase functions designed to control nonlinear optical interference for achieving spectroscopic selectivity.  This presentation will discuss some of the fundamental principles of ultrafast pulse shaping and nonlinear optical interference, illustrate the most salient applications, and consider technologies required to make this concept economically practical.
