TL;DR: In this article, a class of π;-conjugated compounds that exhibit large δ (as high as 1, 250 × 10−50 cm4 s per photon) and enhanced two-photon sensitivity relative to ultraviolet initiators were developed and used to demonstrate a scheme for three-dimensional data storage which permits fluorescent and refractive readout, and the fabrication of threedimensional micro-optical and micromechanical structures, including photonic bandgap-type structures.

TL;DR: In this article, two-photon photopolymer resins were used in the fabrication of complex microarchitectures, such as photonic bandgap structures and tapered waveguides.

TL;DR: In this paper, a wide array of chromophores are developed for 3D optical data storage and 3D microfabrication based on donor-/spl pi/-donor, donor-acceptor-donor or acceptordonor acceptor structural motifs.

TL;DR: In this paper, the authors discuss the recent results on obtaining relatively broadband optical limiting response through the use of such two-photon absorbing chromophores and discuss the requirements for a material to be a good optical limiter are high pulse energy suppression, broad bandwidth, wide temporal response, operation in fast optics and high ambient transmission.
