Narrow Linewidth Lasers for Low-Energy Coherent Communications
Optical Fiber Communication Conference (OFC) 2022, 2022We present chip-scale lasers with ~1Hz fundamental linewidths, ~30Hz integral linewidths, and stability better than 2x10-13 (50ms) enabling energy-efficient, ultra-low residual phase error carrier recovery for DSP-free, high-capacity coherent communications in tomorrow’s data center interconnects.

Tunable fiber laser with narrow linewidth
2016 Photonics North (PN), 2016We demonstrate a narrow linewidth tunable fiber laser based on a tunable fiber Bragg grating, a linear or ring cavity fiber laser and a piece of non-pumped active fiber setup.

Progress and trend of narrow-linewidth lasers
Science China Technological Sciences, 2013High frequency stability, narrow-linewidth lasers have been long dreamed of since the invention of the laser. They have recently developed dramatically due to the advent of optical clocks. State-of-the-art narrow-linewidth lasers have been constructed by using the Pound-Drever-Hall (PDH) technique to lock the laser frequencies to the resonance of ultra-

Narrow linewidth tunable semiconductor laser
2016 Compound Semiconductor Week (CSW) [Includes 28th International Conference on Indium Phosphide & Related Materials (IPRM) & 43rd International Symposium on Compound Semiconductors (ISCS), 2016A full-C band tunable laser equipped with an air-gap suspended waveguide structure for efficient thermal heater tuning is described. It is shown that the monolithic tunable laser can simultaneously meet the requirements for the output power, side-mode suppression ratio, and spectral linewidth for 16-QAM coherent communication system.

Narrow-linewidth tunable ArF* excimer-laser source
IEEE Journal of Quantum Electronics, 1981The generation of narrow-linewidth tunable radiation from excimer lasers has been a topic of considerable investigation recently.1 Because of the short laser wavelengths generated, such sources are ideal tools for multiphoton spectroscopy in the VUV.2 Because conventional excimer lasers generally operate with broadband laser output and poor beam ...

Narrow-linewidth stimulated Brillouin fiber laser and applications
Optics Letters, 1991A stimulated Brillouin fiber ring laser with a spectral width of 2 kHz and an intrinsic linewidth of less than 30 Hz has been demonstrated. Applications of such a laser include laser linewidth narrowing, microwave frequency generation, high-rate amplitude modulation, and optical inertial rotation sensing.

Narrow linewidth operation of a flashlamp-pumped dye laser
Applied Optics, 1982The authors describe a flashlamp-pumped dye laser system that produces more photons per laser pulse than in nitrogen or Nd:YAG laser-pumped dye lasers. The system uses both a grazing incidence grating and a Littrow mounted grating in conjunction with an elliptical cavity.

Ultra-narrow-linewidth Brillouin/Erbium Fiber Laser
Conference on Lasers and Electro-Optics, 2017Ultra-narrow-linewidth lasers are of great interest in many applications, such as precise spectroscopy, optical communications, and sensors. Stimulated Brillouin scattering (SBS), as one of the main nonlinear effects in fibers, is capable of generating narrow-linewidth light emission. We establish a compact Brillouin/erbium fiber laser (BEFL) utilizing
