Control Strategy of an Integrated Tunable Laser With a Single Intra-Cavity AMZI Filter
Asymmetric Mach-Zehnder interferometers (AMZIs) can, in principle, enable continuous wavelength tuning of a laser when used as intra-cavity filters.Their simplicity and good compatibility with generic foundry platforms are major advantages.However, the difficulty to develop a well-defined and robust control strategy is an important drawback which r
