Drastic effects of damping mechanisms on the third-order optical nonlinearity
We have investigated the optical response of superradiant atoms, which undergoes three different damping mechanisms: radiative dissipation (γr), dephasing (γd), and nonradiative dissipation (γn). Whereas the roles of γd and γn are equivalent in the linear susceptibility χ , the third-order nonlinear susceptibility χ drastically depends on the ratio of γd and γn: When γd ≪ γn, χ (3) is essential...
متن کاملThe Third Order Nonlinear Optical behavior of Poly Ether Urethane
Poly (ether) urethane close/open cell (PEUCC/PEUOC) has been prepared by using in situ polymerization approach. The third-order optical nonlinearities of dissolved samples in DMF were characterized by Z-scan technique at the measurement wavelength of 532 nm. The synthesized samples were also examined by optical microscopy and UV-Vis absorption spectroscopy. The nonlinear refractive (NLR) indice...
متن کاملAggregation-induced emission on benzothiadiazole dyads with large third-order optical nonlinearity.
Two kinds of D-A molecular of (4-(4-(9H-carbazol-9-yl)phenyl))-7-nitrobenzothiadiazole (BSC) and 4-((4-(9H-carbazol-9-yl)phenyl)ethynyl)-7-nitrobenzothiadiazole (BEC) containing carbazole moieties as the donor were synthesized. X-ray crystal data elucidated the multiple intermolecular interactions. They exhibit distinctly different self-assembly behaviours. The nonlinear optical properties were...
متن کاملMicroscopic cascading of second-order molecular nonlinearity: New design principles for enhancing third-order nonlinearity.
Herein, we develop a phenomenological model for microscopic cascading and substantiate it with ab initio calculations. It is shown that the concept of local microscopic cascading of a second-order nonlinearity can lead to a third-order nonlinearity, without introducing any new loss mechanisms that could limit the usefulness of our approach. This approach provides a new molecular design protocol...
