Tailorable Brillouin Light Scattering in a Lithium Niobate Waveguide

Applied Sciences, 2021
Stimulated Brillouin scattering (SBS) lasers based on silicon waveguides with large SBS gain have been widely used in frequency tunable laser emissions, mode-locked pulse lasers, low-noise oscillators, optical gyroscopes and other fields.

A novel two-section tunable discrete mode Fabry-PÉrot laser exhibiting nanosecond wavelength switching [PDF]

, 2008
A novel widely tunable laser diode is proposed and demonstrated. Mode selection occurs by etching perturbing slots into the laser ridge. A two-section device is realized with different slot patterns in each section allowing Vernier tuning.

Pulse Narrowing and RF Linewidth Reduction of Integrated Passively Mode-Locked Laser in Anticolliding Design by Means of Spectral Tuning

IEEE Photonics Journal, 2016
In this paper, we present the first tunable extended cavity integrated passively mode-locked laser realized in an anticolliding design. The laser is realized as an InP-based photonic integrated circuit.
