Using Loss to Narrow Plasmon Linewidths

Imaging and Applied Optics Congress, 2020
Lossy materials can be used in nanoplasmonic systems to narrow plasmon linewidths, which is desirable for biosensing applications. A scattering cross section linewidth of about 30 nm is found for gold nanoparticles in the lossy P3HT.

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.

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.

Narrow-linewidth quantum cascade laser at 86  μm

Optics Letters, 2014
We report on a narrow-linewidth distributed-feedback quantum cascade laser at 8.6 μm that is optical-feedback locked to a high-finesse V-shaped cavity. The spectral purity of the quantum cascade laser is fully characterized using a high-sensitivity optical frequency discriminator, leading to a 1 ms linewidth of less than 4 kHz and a minimum laser ...

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 ...

Integrated-optic, narrow-linewidth laser

Applied Physics Letters, 1986
We report the demonstration of the single-frequency and narrow-linewidth (<100 kHz) operation of an extended cavity laser consisting of a Ti:LiNbO3 single-mode waveguide circuit and an InGaAsP waveguide gain medium. A parallel coupled cavity, electro-optic elements for tuning the resonant frequencies of the cavities, and an external phase ...

Linewidth narrowing in Brillouin fiber lasers

Conference Digest. 2000 International Quantum Electronics Conference (Cat. No.00TH8504), 2005
Summary form only given. Contrary to lasers with population inversion, the Brillouin fiber laser is a light source which is very sensitive to the phase noise of the pump laser. This property is attributable to the strong nonlinear coupling between the two optical waves and the acoustic wave interacting inside the fiber.

CMOS photodiodes for narrow linewidth applications

2011 IEEE SENSORS Proceedings, 2011
In recent years CMOS image sensors have gained a major market share for general imaging applications. However, when standard CMOS image sensors are employed in applications that require the detection of light with a very small spectral width, like 3D-time-of-flight imaging or other applications with laser light illumination, problems arise, that are ...

Tunable fiber laser with narrow linewidth

2016 Photonics North (PN), 2016
We 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.
