6 February 2007 Waveguides and devices in silicon photonics: polarization independence
Author Affiliations +
Silicon Photonics is experiencing a significant increase in interest due to emerging applications and several high profile successes in device and technology development. One of the most prominent trends in silicon photonics recently has been a trend towards miniaturising waveguides. The shrinking of the device dimensions provides advantages in terms of cost and packing density, modulation bandwidth, improved performance in resonant structures, and an increase in optical power density within the devices. In this paper we analyse several silicon photonics devices based on both small rib and strip waveguides. We have previously reported on issues related to single mode propagation and polarisation independence of silicon waveguides, and produced design rules for such small waveguides that are reviewed here. We have previously reported a modulator based on a small rib waveguide with the height of < 500nm for high speed operation. However, in this paper we consider slightly larger designs to accommodate polarisation independence. Finally we discuss the characteristics of ring and racetrack resonators based on both rib and strip waveguides and methods of improving free spectral range whilst considering polarization effects, and the difficulty in coupling to such strip waveguide based devices. Both theoretical and experimental results are presented. The maximum free spectral range that we have demonstrated experimentally is approximately 43nm.
