Programmable Silicon Photonics Filter Enables Continuous Laser Wavelength Tuning (UiT, Stanford)

Researchers at UiT The Arctic University of Norway and Stanford University published a technical paper titled “Intracavity Laser Wavelength Tuning by a Programmable Forward-Only Silicon Photonics Interferometer Mesh.”

Abstract Excerpt: “We exploit a recently proposed concept for a programmable, mechanically robust, and tunable nonresonant silicon photonic integrated circuit filter and experimentally demonstrate it for tuning an erbium-doped fiber laser ring cavity. This filter integrates forward-only interferometer meshes together with a waveguide delay line array for fully programmable and tunable filtering. ”
