Abstract

We demonstrate an omnidirectional, retroreflective optical marker in silicon on insulator that enables simultaneous identification and localization of objects. The most important chip requirement - its retroreflectivity - is realized by a large number of equally designed reflective ring resonator circuits, which operate at different angles of the incident light. The markers are characterized by an infrared camera that captures the response during flood exposure by a tunable infrared laser.
