Recent advances within the realization of silica-based planar waveguide circuitry are presented. This ranges from the production methods for planar waveguides, including a novel method based on the utilization of focused UV-laser beams for direct waveguide imprinting, to the functionalities that are embedded into the glass materials and waveguide circuitry. Planar waveguide amplifiers, lasers, and the pursuit to obtain highly nonlinear materials to realize purely glass-based switches, modulators, and wavelength converters are also presented. Furthermore, microring resonators are discussed, and finally the latest results within 2-D photonic bandgap structures are reviewed.

“…An on-chip monolithical integration of the planar amplifiers and/or lasers to other waveguide circuitry is a desired feature 26,27 . In this way, the cumbersome combination of discrete components via optical fibers is avoided.…”

“…A major concern in this monolithical integration is the quality of the connections in terms of loss and reflections between the discrete components and optical functions. One way to obtain the multiple core structures is to make an in-plane patterning of the waveguide core layer with different materials prior to defining the waveguide circuitry 27 . In short, this is done by first depositing one core layer (see section 2.1) followed by a removal (by etching (see section 2.2)) of large parts of this.…”

Recent advances within the realization of silica-on-silicon planar waveguide circuitry are presented. This ranges from the production methods for planar waveguides, including a novel method based on the utilization of focused UV-laser beams for direct waveguide imprinting, to the functionalities that are embedded into the glass materials and waveguide circuitry. The latter includes e.g. optical functions that are realized utilizing phase and amplitude of and resonance conditions for light in waveguide circuitry. We also describe the realization and use of gratings in waveguides. Furthermore, we discuss doping of glass materials used to obtain e.g. amplifiers, lasers, and the pursuit to obtain highly non-linear materials in order to realize purely glass-based switches, modulators and wavelength converters.

“…A great deal of effort has been concentrated on coupling light between different waveguide components and the development of PICs (Laurent-Lund et al 1998;Raburn et al 2002;Shibata et al 2003;Xia et al 2003;Krabe et al 2004). As each component has its own optimised structure for its operation, and different components have different mode sizes and shapes, optical coupling between them becomes a challenge (Regis et al 1999).…”

The Design of Single Mode Large Cross-section Glass-based Waveguides for Photonic Integrated Circuits

This paper presents our recent simulation results and novel designs of single mode large cross-section glass-based waveguides for photonic integrated circuits (PICs). Simulations were performed using an in-house Finite Difference (FD) based mode solver and the FD Beam Propagation Method (FD-BPM). Our simulation results show that this innovative technology could provide a simplified means to couple optical energy efficiently between optical components in a single chip. This would provide the base for the future large-scale integration of optical components in PICs. The novel idea of using single mode large cross-section glass-based waveguides as an optical integration platform is an evolutionary innovative solution for the monolithic integration of optical components, in which the glassbased structures act both as waveguides and as an optical bench for integration. This allows easy and efficient optical coupling between optical components and optical fibres, removing costly and tedious alignment problems and considerably reducing optical coupling losses in PICs. We expect that the glassbased waveguide PICs technology will enable the emergence of a new generation of compact, reliable, high speed, and multifunctional devices.
