A one-dimensional photonic crystal sustaining Bloch Surface Waves (BSWs) is used as a platform for two-dimensional integrated optics. The dielectric platform shows low loss, long propagation distance and high surface field enhancement. In order to study the potential of the platform for future photonic chips, polymer ultra-thin prisms and gratings (~100 nm) are engineered on the top of the plat...

Current optical communication systems rely almost exclusively on multimode fibres for short- and medium-haul transmissions, and are now expanding into the long-haul arena. Ultra-high bandwidth applications are the main drive for this expansion, based on the ability to spatially multiplex data channels in multimode systems. Integrated photonics, on the other hand, although largely responsible fo...

Planar-integrated free-space optics is a highly suitable system concept for realizing densely packed parallel free-space optical short-range interconnects that are compatible with established design and fabrication methods of integrated microelectronics [1]. For use in real-world IT systems, however, the coupling efficiency of such PIFSO interconnects needs to surpass levels of the order of –15...

An integrated spatially non-blocking 2x2 Banyan switch on silicon on insulator (SOI) is demonstrated. The device relying on thermally switched microring resonators has a footprint of less than 0.02 mm2 and shows negligible channel crosstalk. The presented novel switch topology features a high scalability for application in many-core interconnections for network on-chip architectures. Keywords-c...

Increasing scope and applications of integrated optics necessitates the development of automated techniques for physical design of optical systems. A key area of integrated optic design is waveguide routing, which currently lacks the level of automation found in VLSI design. Unlike VLSI, where signal nets are routed with metal layers and vias, integrated optics is a planar technology and lacks ...

A wideband and continuously tunable integrated fractional order photonic Hilbert transformer is proposed and demonstrated. The device is realized by a simple apodised Bragg grating within a germano-borosilicate high birefringent planar substrate, achieving a 120GHz operating bandwidth and fractional order tuning capability. The order of photonic Hilbert transform can be constantly controlled by...

Chip-integrated nanophotonics investigates the interaction of light with nanostructures integrated on a chip. Lying at the intersection of condensed matter physics, optics, nanotechnology, and materials science, nanophotonics draws upon expertise from broad areas of physics and engineering, while presenting major opportunities to advance fundamental physics and transformative photonic technolog...

Almost all direct wafer bonding has been conducted between chemical-mechanically polished substrates or between thin films that were present on top of the polished substrates. Introducing chemical mechanical polishing in the wafer bonding will make a large range of materials suitable for direct wafer bonding, which has found and will find more, applications in integrated circuits, integrated op...
