Linear and nonlinear optical response from Cicadas transparent wings

The wings of some insect species are known to fluoresce under illumination by ultraviolet light. Their fluorescence properties are, however, not comprehensively documented. In this presentation, the optical properties of unknown fluorophores naturally occurring within Cicadas transparent wing, were investigated using both linear and nonlinear optical (NLO) methods, including one- and two-photon fluorescence and second harmonic generation (SHG).
