Short cavity InGaAsP/InP lasers with dielectric mirrors [PDF]

open access: yes, 1983
Short cavity length (38 µm) lasers have been fabricated using a recently developed microcleavage technique. SiO2-amorphous Si multilayer coatings have been evaported on the lasers to obtain high reflectivity mirrors. The lasers have current thresholds as

A Stabilized Single-Longitudinal-Mode and Wide Wavelength Tunability Erbium Laser

open access: yesPhotonics, 2022
An erbium-doped fiber (EDF) laser with quad-ring is designed to reach the broad continuous-wave (CW) tunability and single-longitudinal-mode (SLM) behavior.

Unstable resonator cavity semiconductor lasers [PDF]

open access: yes, 1985
GaAs heterostructure lasers with unstable resonator cavities were demonstrated for the first time with both curved mirrors fabricated by etching. Typical output powers of 0.35 W were observed in a stable, highly coherent lateral mode.

Single Longitudinal Mode Optofluidic Microring Laser Based on a Hollow-Core Microstructured Optical Fiber

open access: yesIEEE Photonics Journal, 2017
A single longitudinal mode microring dye laser based on a simplified hollow-core microstructured optical fiber (SHMOF) is proposed and demonstrated. The dye laser uses a submicron thickness silica microring embedded in the SHMOF as resonator and has the ...

Compound Cavity Passively Q-Switched Single-Longitudinal-Mode Diode-Pumped Laser

open access: yesFrontiers in Physics, 2022
A compact solid-state single-longitudinal-mode (SLM) Q-switched laser based on a compound cavity is demonstrated. SLM operation is achieved through the enhancement of mode competition (via manipulation of the effective reflectivity of the resonator ...

Exploring multi-stability in semiconductor ring lasers: theory and experiment [PDF]

open access: yes, 2009
We report the first experimental observation of multi-stable states in a single-longitudinal mode semiconductor ring laser. We show how the operation of the device can be steered to either monostable, bistable or multi-stable dynamical regimes in a ...

Narrow-Strip Single-Longitudinal-Mode Laser Based on Periodic Anodes Defined by i-Line Lithography

open access: yesIEEE Photonics Journal, 2018
A low-cost regrowth-free narrow-strip single-longitudinal-mode diode laser, based on periodic anodes defined only by i-line lithography is proposed. With the periodic anodes separated by surface insulated grooves acting as a 44th-order gain grating, a ...

Single-Longitudinal-Mode Thulium-Doped Fiber Laser With Sub-kHz Linewidth Based on a Triple-Coupler Double-Ring Cavity

open access: yesIEEE Access, 2022
We propose and demonstrate a stable single-longitudinal mode (SLM) thulium-doped fiber laser (TDFL) with a Fabry- Pérot (F-P) fiber Bragg grating (FBG) filter and a triple-coupler based double-ring cavity (TC-DRC) filter.

A tunable S-plus L-band continuous-wave single-longitudinal-mode fiber-optical parametric oscillator [PDF]

open access: yes, 2011
We demonstrate an all-fiber continuous-wave single-longitudinal-mode fiber-optical parametric oscillator. The output tuning range extends from 1487 to 1541 nm and from 1570 to 1630 nm, which covers the S- and L-bands. Single-longitudinal-mode oscillation
