Narrow-Linewidth Fano Laser

Conference on Lasers and Electro-Optics, 2022
By exploiting Fano resonances, a microscopic laser with a linewidth >20 times smaller than previous microscopic lasers is experimentally demonstrated. We also show that the linewidth can be further improved by engineering the Fano lineshape.

Hybrid integrated narrow-linewidth semiconductor lasers

Applied Optics, 2023
Integrated narrow-linewidth lasers are the key devices in compact coherent optical systems of metrology, sensing, and optical microwave generation. Here, we demonstrate a hybrid integrated laser based on an optical negative feedback scheme.

Wavelength-tunable narrow-linewidth gaseous Raman laser

Applied Optics, 2021
Gaseous Raman lasers cover a range of wavelengths but lack wavelength tunability. Here, a 1 c m − 1 linewidth 532 nm laser was used as a pump laser, and with a narrow-linewidth seed laser injection, a narrow-linewidth first Stokes (S1) Raman ...

Narrow linewidth quantum cascade laser

Conference on Lasers and Electro-Optics, 2020
A narrow linewidth quantum cascade laser was obtained by optical feedback locking to a high finesse linear cavity with locking bandwidth larger than 5 MHz, resulting in an instantaneous linewidth at mHz levels.

Future Narrow Linewidth Lasers

Optical Fiber Communication Conference, 2015
We describe the challenges and solutions for future narrow linewidth lasers with small footprint. We fabricated DR laser array based narrower linewiedth TLS. We introduce ITXA of a co-packaged DFB array based TLS and InP-based modulator.

Narrow linewidth single frequency microfiber laser

Optics Letters, 2012
A compact 2 kHz linewidth single frequency microfiber ring laser is demonstrated. Microfiber, with a diameter of 1.88 μm, which is drawn from an Er(3+)/Yb(3+) co-doped phosphate glass fiber, serves as the gain medium. By using this microfiber, a double-knot resonator with a total length of 1.75 mm is constructed.

Modulatable narrow-linewidth semiconductor lasers

Applied Physics Letters, 1988
We find that using the technique of optical feedback locking, to narrow semiconductor linewidths, does not sacrifice the ability to modulate the laser’s frequency via the injection current. The frequency of a laser is stabilized to a separate Fabry–Perot reference cavity using resonant optical feedback and can be modulated efficiently at frequencies ...
