Title: Scalable and efficient photon generation for integrated optical systems

Abstract:
The generation of correlated or entangled photon pairs using bulk non-linear optical crystals is a mature technology and widely employed as the starting point for many optical experiments.   Scaling such experiments to operate on multiple photon pairs is a non-trivial task and takes large amounts of lab-space to accomplish.  Recent advances in on-chip photonic systems, originally designed for telecommunications applications, provide an alternative to bulk optical systems for the generation and manipulation of light.  These devices are extremely compact, allowing for dense optical device integration in mm2 areas and opening up the prospect for scalable optical experimental setups on a single chip.

Recent work demonstrating correlated and entangled photon generation from ultra-compact silicon resonator devices will be presented.  Tuning of the non-linear efficiency is achieved using simple electronic control of the chip.  The issue of pump light filtering is also addressed, as this presents a major obstacle to producing fully on-chip photon generation and manipulation circuits.
