“…This is referred to as excited-state absorption (ESA). The two slight humps on either side of focus of the open-aperture z -scan signature indicates the presence of the feeble saturable absorption (SA) property of the system, as a result of ground-state bleaching, which is common in the BODIPY-based small molecules . The obtained effective nonlinear absorption coefficient (β eff ) is 55 cm/GW, and the saturation intensity is 0.005 GW/cm 2 .…”

The contribution of ESA is also confirmed by calculating the ratio of the ESA cross section (σ ex ) to the ground-state absorption cross section (σ 0 ).…”

Light confinement structures offer tantalizing applications in a wide variety of areas where light–matter interactions play a crucial role. Considering optical nonlinearity, light localization in nanoscale mode volumes may trigger nonlinear optical activity even at relatively low input optical powers. Here, we demonstrate the excitation of the Tamm plasmon mode of a metal–polymer photonic crystal hybrid structure, resonantly invoking absorptive nonlinear behavior of organic BODIPY dye incorporated in the spacer layer. Third-order nonlinear optical measurements are carried out using the z-scan technique with a Q-switched Nd:YAG laser delivering 7 ns pulses at 532 nm. While the bare sample exhibits negligible optical nonlinearity, the sample in the Tamm plasmon structure showed a large nonlinear absorption coefficient of 1.2 × 106 cm/GW at 0.27 GW/cm2 peak excitation intensity. Our results demonstrate a simple and efficient method to create a nonlinear nanophotonic platform valuable for applications in all-optical information processing.

“…Various substituents linked to the framework of the bispyrrole-boron were studied. [197][198][199][200][201][202][203][204][205][206][207][208][209][210][211][212][213][214][215][216] Although, most of the studies reported a six-membered ring formation, in 2016, Shen and co-workers reported 197 both five and six membered ring formation using hydrazine-Schiff base linked bispyrrole. Compound 217 (six-membered-ring) showed efficient solidstate fluorescence owing to the weak intermolecular interactions and a large Stokes shift, whereas, compound 218 (fivemembered-ring) has a small Stokes shift which results in weak fluorescence in the solid-state via self-quenching.…”

“…Interestingly, both the enantiomers showed reversal aggregation-induced circular dichroism from solution to aggregation in the THF/H 2 O mixture owing to the axial chirality transfer in the aggregation state. BOPHY derivatives were also used for the detection of Cu 2+ ions, 205 as non-linear optical materials, 212 and as photocatalysts. 211,215 Werz and co-workers explored the synthesis of a new class of boron based fluorophores 224, 225 (Fig.…”
