“…p-Conjugated organic molecules are an important class of multi-photon absorbing materials, which have attracted increasing attention due to their versatile applications in two-photon cellular imaging, [1,2] optical power limiting, [3,4] multi-photon pumped lasing, [5] three-dimensional optical storage, [6,7] and photodynamic therapy. [8,9] Large two-photon absorption (TPA) cross-sections have often been associated with the extent of conjugation length (effective p-delocalization), which leads to an extended charge separation (a large pconjugated system).…”

This paper reports on the two‐photon absorption (TPA) and related up‐converted emission properties of a novel series of chromophores containing ladder‐type oligo‐p‐phenylenes with various π‐conjugation lengths. The design and synthesis of these ladder‐type two‐photon chromophores are first discussed. An increase in the π‐conjugated length of the ladder‐type oligo‐p‐phenylene for these chromophores leads to an increase in TPA cross‐section together with an increased fluorescence quantum yield. These chromophores exhibit high fluorescence quantum yields because of the rigid planar structure of the ladder‐type oligomers. The chromophore with an enhanced TPA cross‐section together with an increased fluorescence quantum yield would provide significant benefits for two‐photon excited fluorescence based applications. An improved optical limiting behavior was also demonstrated using the ladder‐type pentaphenylene cored chromophore.

“…The energies of absorbed photons should satisfy the resonance condition. This process, referred to as the two-photon absorption, has many interesting characteristics, with direct implication on technological applications [1][2][3][4][5]. Aiming at applications in photonics, a great effort has been put into synthesizing materials with high twophoton absorption cross-sections, as well as understating the relationship between the molecular structure and the nonlinear optical processes [6][7][8][9][10].…”

a b s t r a c tThis work investigates the two-photon absorption spectrum of perylene tetracarboxylic derivatives using the white-light continuum Z-scan technique. Perylene derivatives present relatively high two-photon absorption cross-section, which makes them attractive for applications in photonics. Because of the spectral resolution of the white-light continuum Z-scan, we were able to observe a well defined structure in the two-photon absorption spectrum, composed by two distinct peaks. These peaks, as well as the resonant enhancement of the nonlinearity, were modeled using the sum-over-states approach considering a four-level energy diagram with two final two-photon states. The existence of such states was confirmed using the response function formalism within the DFT framework.

“…Direct two-photon pumping to achieve population inversion in organic systems usually requires very high peak power. However, using our multifunctional chromophores, discussed above, we have achieved up-conversion lasing by direct two-photon pumping (2)(3)(4). The chromophore APSS was pumped by 5 nanosecond pulses from a dye laser which in turn was pumped by the 532 nm frequency doubled output of a pulse Nd-Yag laser.…”

Multifunctional materials will play an important role in the development of Photonics Technology. This paper describes novel multifunctional polymeric composites for applications in both active and passive photonic components. On the molecular level, we have introduced multifunctionality by design and synthesis of chromophores which by themselves exhibit more than one functionality. At the bulk level, we have introduced the concept of a "multiphasic nanostructured composites" where phase separation is controlled in the nanometer range to produce optically transparent bulk in which each domain produces a specific photonic function. Results are presented from the studies of up-converted twophoton lasing, two-photon confocal microscopy, optical power limiting, photorefractivity and optical channel waveguides to illustrate the application of the multifunctional optical composites.The development of Photonics or Optical Technology is crucially dependent on the availability of materials which can simultaneously exhibit more than one property. These are multifunctional materials. MultifÀinctionality is exhibited by a material when it simultaneously performs two or more different functions. Also, a combination of two different functionalities can give rise to a new effect useful for photonics technology. An example is photorefractivity which is produced by the combined action of nonlinear electro-optic effect and photoconductivity. In this paper, the nanostructure control used in our laboratory to introduce multifunctionality will be presented. On the molecular level, we have introduced multifunctionality by design and synthesis of chromophores which by themselves exhibit more than one functionality (1). Examples are chromophores which show strong two-photon absorption and strong fluorescence. We have utilized the combined action of these two functions to achieve up-conversion lasing (1-4). We have also designed and synthesized segmented co-polymers and sidechain co-polymers consisting of different groups which perform different functions. Thus we have produced multifunctional photorefractive polymers which exhibit both
