    No full text
    From October 18 to October 23, 2009 the Dagstuhl Seminar 09431 ``From Form to Function \u27\u27 was held in Schloss Dagstuhl~--~Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available

    Direct Laser Writing Of Three-Dimensional Photonic-Crystal Templates For Telecommunications

    The past decade has witnessed intensive research efforts related to the design and fabrication of photonic crystals1,2. These periodically structured dielectric materials can represent the optical analogue of semiconductor crystals, and provide a novel platform for the realization of integrated photonics. Despite intensive efforts, inexpensive fabrication techniques for large-scale three-dimensional photonic crystals of high enough quality, with photonicbandgaps at near-infrared frequencies, and built-in functional elements for telecommunication applications, have been elusive. Direct laser writing by multiphoton polymerization3 of a photoresist has emerged as a technique for the rapid, cheap and flexible fabrication of nanostructures for photonics. In 1999, so-called layer-by-layer4 or woodpile photonic crystals were fabricated with a fundamental stop band at 3.9 μm wavelength5. In 2002, a corresponding 1.9 μm was achieved6, but the important face-centred-cubic (f.c.c.) symmetry was abandoned. Importantly, fundamental stop bands or photonic bandgaps at telecommunication wavelengths have not been demonstrated. In this letter, we report the fabrication - through direct laser writing - and detailed characterization of high-quality large-scale f.c.c. layer-by-layer structures, with fundamental stop bands ranging from l.3 to 1.7 μm

    Shrinkage Precompensation Of Holographic Three-Dimensional Photonic-Crystal Templates

    Quantification and precompensation of photoresist anisotropic shrinkage of the holographic three-dimensional photonic-crystal templates solves the problem of template size reduction and effects the photonic band gap (PBG). During the processing of the of SU-8 photoresist system in holographic lithography, a cationic polymerization reaction takes place that results in a reduction of the free volume of the polymer network, which in turn leads to volume shrinkage. It was required to expose the photoresist to an appropriately spatially elongated interference pattern to precompensate the distortion, which results in a final photoresist crystal with the desired symmetry, after unidirectional shrinkage. Scanning electron microscopy (SEM) of the inner surfaces fabricated by focused-ion beam (FIB) milling was used for the quantification of the effective material shrinkage. A scattering matrix was employed to calculate the transmission and reflection of the samples
