“…Subsequently, single-crystal silicon waveguides [25], [26] were soon demonstrated, initially fabricated using highly doped silicon substrates. Various substrate configurations, such as silicon-on-sapphire (SOS) [29], silicon germanium [30], and SOI [9], [31], [32] were also studied. The SOI platform among them, first reported for optical applications in 1988 [31], has by far, become the most popular among the silicon-based waveguide systems.…”

| In this paper, we present a brief history of silicon photonics from the early research papers in the late 1980s and early 1990s, to the potentially revolutionary technology that exists today. Given that other papers in this special issue give detailed reviews of key aspects of the technology, this paper will concentrate on the key technological milestones that were crucial in demonstrating the capability of silicon photonics as both a successful technical platform, as well as indicating the potential for commercial success. The paper encompasses discussion of the key technology areas of passive devices, modulators, detectors, light sources, and system integration.In so doing, the paper will also serve as an introduction to the other papers within this special issue.

“…In other ways, it is in its infancy, with some major advances being reported only very recently. The first waveguides were reported in the mid 1980s, in silicon on doped silicon [1], silicon on sapphire [2], silicon germanium [3], and Silicon on Insulator (SOI) [4,5]. The silicon on insulator platform, first reported in 1989, has by far, become the most popular of the four waveguide systems, and it is this platform that has formed the core of the work carried out by the Silicon Photonics Group at the University of Surrey, which was also established in 1989.…”

Silicon Photonics is experiencing a dramatic increase in interest due to emerging applications areas and several high profile successes in device and technology development. Despite early work dating back to the mid 1980s, dramatic progress has been made in recent years. Whilst many approaches to research have been developed, the striking difference between the work of the early to mid 1990s, and more recent work, is that the latter has been associated with a trend to reduce the cross sectional dimensions of the waveguides that form the devices. The question arises therefore as to whether one should move to very small strip waveguides (silicon wires) of the order of 250nm in height and a few hundred nanometres in width for improved device 2 performance but with little hope of polarisation independence, or to utilise slightly larger rib waveguides that offer more opportunity to control the polarisation dependence of the devices. In this paper we discuss devices suitable for one approach or the other and present designs associated both with strip and rib waveguides. In particular, we present designs of polarisation independent ring resonators with FSRs up to 12nm, we propose modulators for bandwidths in the 10s of GHz regime, and we present grating based couplers for rib and strip waveguides, and/or for wafer scale testing, as well as a novel means of developing Bragg gratings via ion implantation.

In this paper we present our work on three silicon waveguide structures that are suitable for three different wavelength regions: near-, mid-and far-infrared. Design rules for standard rib SOI waveguides are given. Both single mode and polarisation independence in these waveguides are discussed. A hollow core waveguide suitable for gas sensing applications in the mid-infrared wavelength region is also analysed. Finally, fabrication and experimental results for free standing waveguides, which may find application in the mid and perhaps far-infrared wavelength region, are presented.
