We are excited to announce our latest publication: “Direct Intensity and Phase Modulation for QKD Transmitter via Optical Injection Locking”, presented at Europe-EQEC 2025.
This work presents a transmitter design that directly implements both intensity and phase modulation in a QKD system by leveraging optical injection locking of a laser diode. The approach reduces the need for bulky external modulators while maintaining security-relevant state preparation.

We believe the methodology will be of interest to those working in quantum communications, photonic transmitter design, and secure optical network architectures.
