“…[ 36 ] In this study, two binary aperiodic sequences with different properties in reciprocal space are encoded into three-dimensional simple cubic photonic crystals by varying the distance between lattice planes along the three main axes (Figure 3 d).

functional elements, chiral photonic crystals, photonic metamaterials and quasicrystals. With this technology becoming commercially available, [ 1 ] many novel ideas have been realized by scientists around the world. Some of these developments can already be seen as new research areas enabled by 3D µ-printing.Many excellent reviews of the underlying technology have recently been published, and we give here just a short selection. [2][3][4][5] With the present progress report we want to summarize the tremendous technological development during the last fi ve years as well as to give an overview over some vastly growing research fi elds enabled by this development. As the number of research papers based on 3D µ-printing as enabling technology is exploding, we intend to categorize the most recent developments to identify future research directions and possible novel fi elds for the years to come. Recent Technological Advances in 3D µ-PrintingFrom the fi rst proof-of-principle in 1997, [ 6 ] the µ-printing community has continuously been expanding the structuring capabilities of µ-printing systems overcoming limitations such as structuring speed, sample volume, complicated pre and post processing, as well as minimum feature size and resolution. Progress is made along two directions: First, extending the aforementioned benchmarks of µ-printing systems. Second, techniques that move µ-printed structures towards functional devices. These two directions obviously are intertwined and require interdisciplinary research efforts on new photocurable materials, complex light-matter interaction, reaction kinetics as well as processes on a molecular level infl uencing structure formation. The most infl uential technological advances are summarized in this section.Section 2.1. covers recent work leading to a tremendous increase of the capabilities of µ-printing systems. Section 2.2. describes superresolution concepts exploiting light-matter interactions to achieve smaller feature sizes and higher structural resolution. Section 2.3. reviews spatial light modulator (SLM) based laser lithography providing additional degrees of freedom by shaping the wavefront of the laser beam. Laser Sources, Scanning Devices, and Writing GeometryThe high complexity of ultrafast fs-lasers drives the community to look for alternative laser sources, leading to cost and In this progress report the development of three-dimensional µ-printing and its impact as an enabling technology onto different scientifi c fi elds is reviewed. Driven by direct laser writing via two-photon absorption, the technology has reached a level of maturity and ease of application such that 3D printing on the micrometer scale can now be considered. While the underlying technology is still developing towards higher resolution and increasing speed of fabrication, the last fi ve years have seen new fi elds rising that were obviously enabled by 3D µ-printing. Among the recent technological developments discussed in this progress report are the fi elds of super-resolution lithography ...

“…The structure then is built layer by layer (starting at the glass sheet) by moving the objective in the z-direction. To minimize the stress onto the structure that occurs due to shrinkage during development, the structure is put onto a grid [32,33]. Besides leading to uniform shrinking of the structure, it also helps to remove the unpolymerized resist from the waveguide channels during development.…”

Dynamic defects in photonic Floquet topological insulators

Edge modes in topological insulators are known to be robust against defects. We investigate if this also holds true when the defect is not static, but varies in time. We study the influence of defects with timedependent coupling on the robustness of the transport along the edge in a Floquet system of helically curved waveguides. Waveguide arrays are fabricated via direct laser writing in a negative tone photoresist. We find that single dynamic defects do not destroy the chiral edge current, even when the temporal modulation is strong. Quantitative numerical simulation of the intensity in the bulk and edge waveguides confirms our observation.

We benefit from a highly dynamic and reversible induction scheme at realizing largely elongated photonic structures that offer excellent interaction distances.…”

As light localization becomes increasingly pronounced in photonic systems with less order, we investigate optically induced two-dimensional Fibonacci structures which are supposed to be amongst the most ordered realizations of deterministic aperiodic patterns. For the generation of corresponding refractive index structures, we implement a recently developed incremental induction method using nondiffracting Bessel beams as waveguide formation entities. Even though Fibonacci structures present slightly reduced order, we show that transverse light transport is significantly hampered here in comparison with periodic lattices that account for discrete diffraction. Our experimental findings are supported by numerical simulations that additionally illustrate a development of transverse light localization for increasing propagation distance.
