Silicon photonics offers a low-cost platform for building large-scale photonic devices and circuits, potentially replicating the success of silicon microelectronics in photonics. Photonic crystal nanostructures provide novel physical mechanisms, such as the slow-light effect and superprism effect, to reduce the size and improve the performance of silicon photonic devices. This talk will review our recent work on silicon-compatible waveguides, including slow-light photonic crystal waveguides, for use as on-chip optical delay lines. Particularly, some fundamental physical issues of photonic crystal waveguides such as slow-light loss will be addressed. Optical delay lines have applications in phased array antennas, optical signal processing, and optical modulation. It will be shown that the current slow-light loss levels are sufficient for some applications, whereas challenges remain in other applications. This talk will also review our work on dual racetrack silicon micro-resonators for quadrature amplitude modulation. Potential applications of these device components in optical communications, optical interconnects, laser beam steering, and optical signal processing will be discussed.
