High‐throughput sequencing has laid the foundation for fast and cost‐effective development of phylogenetic markers. Here we present the program discomark, which streamlines the development of nuclear DNA (nDNA) markers from whole‐genome (or whole‐transcriptome) sequencing data, combining local alignment, alignment trimming, reference mapping and primer design based on multiple sequence alignments to design primer pairs from input orthologous sequences. To demonstrate the suitability of discomark, we designed markers for two groups of species, one consisting of closely related species and one group of distantly related species. For the closely related members of the species complex of Cloeon dipterum s.l. (Insecta, Ephemeroptera), the program discovered a total of 78 markers. Among these, we selected eight markers for amplification and Sanger sequencing. The exon sequence alignments (2526 base pairs) were used to reconstruct a well‐supported phylogeny and to infer clearly structured haplotype networks. For the distantly related species, we designed primers for the insect order Ephemeroptera, using available genomic data from four sequenced species. We developed primer pairs for 23 markers that are designed to amplify across several families. The discomark program will enhance the development of new nDNA markers by providing a streamlined, automated approach to perform genome‐scale scans for phylogenetic markers. The program is written in Python, released under a public licence (GNU GPL version 2), and together with a manual and example data set available at: https://github.com/hdetering/discomark.

“…This pioneering work proved that BSW propagation may be easily managed by simple lithographic nanostructuring of the top layer of the photonic crystal. Since then, a wide spectrum of complex photonic devices has been demonstrated, including lenses [20], a prism [21], square and round gratings [22,23], a subwavelength focusing device [24], a polarisation-sensitive beam splitter [25], and a disk resonator [26]. However, the basic and the most important element of integrated photonics-waveguide-remains not fully studied.…”

Bloch Surface Wave Photonic Device Fabricated by Femtosecond Laser Polymerisation Technique

Abstract:We applied femtosecond laser polymerisation technique to fabricate a novel Bloch surface wave integrated photonic device with a compact coupling scheme. The device consisted of a waveguide, coupling and decoupling gratings and focusing and defocusing triangles. We manufactured an array of devices with varying geometrical parameters of waveguide. Excitation and propagation of Bloch surface wave waveguide modes were studied by direct and back focal plane imaging. The obtained results prove that the maskless and flexible femtosecond laser polymerisation technique may be applied for fabrication of Bloch-surface-wave based integrated photonics.

“…This complementary character to the SPP makes the BSW a good candidate for integrated photonic devices, and this has inspired much research in recent years. Devices with basic functionalities have been explored, e.g., a prism demonstrating refraction of the propagating surface wave [4], a grating generating 2D Talbot images on the chip surface [4], a refractive micro lens for focusing [5], and waveguide components [6][7][8]. All these elements came into reach by adding a structured device layer on the top of the stratified media.…”

Abstract:In order to enlarge the capability for in-plane manipulation of the Bloch surface wave (BSW), we investigate 2D gradient index (GRIN) optical components using a finite-difference time-domain (FDTD) numerical method. To ease difficulties in fabrication to acquire a continuous index profile of GRIN optical components, we propose a stepwise index profile. For 2D surface wave devices, such discrete index steps can be achieved by stepwise structuring of the top layer, also called the device layer. For the demonstration of the stepwise GRIN optics concept, we consider a Luneburg lens, which is a good example of the GRIN optical component that produces a strong focal spot on the shadow-side curvature of the lens. The limited index contrast of the BSW systems loosens the confinement of the focal spot. A mitigation plan is to elongate the circular geometry to the prolate ellipse. BSW-based Luneburg lenses with a relatively small number of steps and an elliptical geometry are demonstrated with comparable performances to a standard Luneburg lens.
