Exploring the feedback limits of quantum dot lasers for isolator-free photonic integrated circuits

By accessing the coherence-collapse regime under strong on-chip feedback, quantum dot lasers demonstrate unprecedented robustness, supporting penalty-free operation and practical isolator-free photonic integrated circuits.

3D integration enables ultralow-noise isolator-free lasers in silicon photonics

Three-dimensional integration of distributed-feedback lasers and ultralow-loss silicon nitride waveguides results in ultralow-noise lasers without the need for optical isolators.

Broadband quantum-dot frequency-modulated comb laser

This work investigates the optical nonlinearities of quantum-dot mode-locked lasers and demonstrates how to generate the amplitude-modulated and the frequency-modulated comb independently from a single device.
