Na próxima terça-feira (8), o Departamento de Física realiza mais uma edição do Seminário de Óptica. Dessa vez, o tema será “Propagation of ultrashort and ultraintense optical pulses in a nonlinear media” e o seminário será ministrado pelo doutorando André Chaves. O evento será no auditório do Departamento de Física, a partir das 14h.

Resumo

Supercontinuum generation (SCG) is a nonlinear pulse propagation phenomenon where an extremely wide optical spectrum is coherently produced from an initially nearly monochromatic laser beam. Many are the nonlinear effects and physical mechanisms behind the observation of SCG, such as the self-phase modulation (SPM), self-steepening and the group velocity dispersion (GVD). In this seminar, I will discuss the formation of high-order temporal solitons under normal and anomalous dispersion using the 1-D approximation, which is valid for waveguides and soft focusing conditions.
