“…If the observed resolution deterioration is a generic problem of coinitiators, this issue would be of great importance for the entire DLW community. It would influence the resolution of many photoinitiating systems for regular DLW, the resolution of existing photoinitiating systems for STED‐like DLW, and the resolution of potential future photoinitiating systems for true STED‐DLW like dye‐amine systems. Clearly, this issue demands for further interdisciplinary investigation which is beyond the scope of this paper.…”

Mode properties of circularly symmetric waveguides with one special type of bianisotropy are studied using finite element approach. We find that the polarization degeneracy in circularly symmetric waveguides can be eliminated, by introducing intrinsic crossing coupling between electric and magnetic moments in the constituent units of the waveguide media. Breaking the polarization degeneracy in high order mode groups is also confirmed numerically. With the bianisotropic parameters chosen in this work, the x and y-polarized modes remain decoupled. Typically, the y-polarized modes remain completely unchanged, while the x-polarized modes are turned into leaky modes that are lossy along propagation direction. A perturbation model from coupled mode theory is developed to explain the results and shows excellent agreement. Such asymmetric behavior between different polarizations might be feasible and useful for developing compact polarizers in terahertz or mid-infrared regime.

“…[80] They were able to achieve fabrication at average powers of less than 1 mW with a Ti:sapphire oscillator tuned to 800 nm. Watanabe and co-workers have used this iodonium coinitiator with their cyano-substituted, imino-backbone chromophore and a tertiary amine to enable fabrication with acrylates in dioxane.…”

“…[63,88] Two groups have reported the use of custom-made PAGs. Ober and co-workers [89] used the coumarin iodonium salt first reported by Li et al [80] because of its high TPA cross section. Marder, Perry, and co-workers adapted their high-d molecules with the bis(styryl)benzene core into PAGs by changing the pendant groups to contain sulfonium moieties.…”

Chemical and physical processes driven by multiphoton absorption make possible the fabrication of complex, 3D structures with feature sizes as small as 100 nm. Since its inception less than a decade ago, the field of multiphoton fabrication has progressed rapidly, and multiphoton techniques are now being used to create functional microdevices. In this Review we discuss the techniques and materials used for multiphoton fabrication, the applications that have been demonstrated, as well as those being pursued. We also consider the outlook for this field, both in the laboratory and in industrial settings.

“…[80] Mit einem auf 800 nm eingestellten Ti:Saphir-System gelang ihnen eine Mikrofabrikation bei einer durchschnittlichen Leistung unter 1 mW. Watanabe und Mitarbeiter setzten diesen Iodonium-Coinitiator zusammen mit ihrem cyansubstituierten Imin-Chromophor und einem tertiären Amin zur Mikrofabrikation mit Acrylaten in einer Dioxanlösung ein.…”

“…[63,88] Zwei Arbeitsgruppen haben selbst hergestellte PAGVerbindungen eingesetzt. Ober und Mitarbeiter [89] verwendeten das Cumarin-Iodoniumsalz-System von Li et al [80] wegen des großen TPA-Querschnitts. Marder, Perry und Mitarbeiter modifizierten ihre Bis(styryl)benzol-Verbindungen, die hohe d-Werte aufweisen, indem sie Sulfoniumgruppen in die Seitenketten integrierten.…”

Mehrphotonen‐Mikrofabrikation

et al. 2007

View full text Add to dashboard Cite

Chemische und physikalische Prozesse, die auf Mehrphotonenabsorption beruhen, ermöglichen die Herstellung komplexer dreidimensionaler Mikrostrukturen mit einer Auflösung von 100 nm. Seit der experimentellen Realisierung der Mehrphotonenabsorption vor nicht einmal zehn Jahren wurden in diesem Bereich rasch Fortschritte erzielt, und Mehrphotonentechniken werden heute für die Herstellung funktionsfähiger Mikrosysteme eingesetzt. In diesem Aufsatz diskutieren wir die Techniken und Materialien, die für die Mehrphotonen‐Mikrofabrikation verwendet werden, sowie bereits beschriebene und gegenwärtig angestrebte Anwendungen. Wir betrachten auch die Perspektiven dieses Felds für Forschung und Industrie.
