Abstract

This letter investigates system performance of slow-light variable optical buffer based on cascaded stages of tunable silica microresonator rings. Continuous tunability is achieved by adjusting the resonance of each ring on the compact photonic integrated circuit. The all-pass configuration allows selectively applying variable delays to wavelengths of choice without losing any packets in an optical packet switching network.
