We demonstrate adiabatic nanofocusing of few-cycle light pulses using ultrasharp and ultrasmooth single-crystalline gold tapers. We show that the grating-induced launching of spectrally broad-band surface plasmon polariton wavepackets onto the shaft

A pyrene-flavin (isoalloxazine) dyad (PFD) and a phenothiazine-phenylene-isoalloxazine dyad (PPF), dissolved in dichloromethane are characterized by absorption and emission spectroscopy. These dyads are model compounds for flavin based blue-light pho
