Depending on the size of the smallest feature, the interaction of light with structured
materials can be very different. This fundamental problem is treated by different theories. If …

Investigations into the structuring by two-photon polymerization of a nonshrinking,
photosensitive, zirconium sol− gel material are presented. This hybrid material can be …

We present a new method for increasing the resolution of direct femtosecond laser writing by
multiphoton polymerization, based on quencher diffusion. This method relies on the …

In a random laser the optical feedback is provided by scattering rather than by an optical
cavity. Then, since its emission characteristics are very susceptible to the scattering details, it …

Because of their spontaneous nanostructure thin films behave differently from bulk materials
of equivalent chemical composition. Depending both on material and deposition technique …

In this work, we have synthesized and characterized a novel, titanium-containing hybrid
material that can be structured three-dimensionally using two-photon polymerization. We …

Two‐photon polymerization of photosensitive materials has emerged as a very promising
technique for the fabrication of photonic crystals and devices. We present our investigations …

The growing need for classical as well as quantum optical sensing places increasingly
stringent requirements upon the desired characteristics of the engendered fields …

Context. Within the framework of the second-generation instrumentation of the Very Large
Telescope Interferometer of the European Southern Observatory we have developed the …

The use of thin polymer films in optical planar integrated optical circuits is rapidly increasing.
Much interest, therefore, has been devoted to characterizing the optical and mechanical …
