Dynamic optical injection of mode-locked quantum-dot lasers for high-speed optical sampling (Invited Paper)

29 January 2025 • 2:20 PM - 2:50 PM PST | Moscone West, Room 2008 (Level 2)

Abstract

We show how dynamic optical injection can be used for rapid and wide tunability of the pulse repetition rate of a mode-locked quantum-dot laser. We harness this capability to demonstrate record scan rates in high-speed optical sampling by cavity tuning (OSCAT) and parallel heterodyne interferometry via rep-rate exchange (PHIRE).
