A Novel Repetition Rate Adjustable SBS-Based Q-Switched Fiber Laser

open access: yesIEEE Photonics Journal, 2020
We experimentally demonstrated a novel repetition rate adjustable SBS-based Q-switched fiber laser. An inserted Fabry-Perot interferometer formed by two non-contact end faces of two FC/PC fiber connectors was inserted to help the system stabilize ...

Broadband Tuning (170nm) of InGaAs Quantum Well Lasers [PDF]

open access: yes, 1990
The wavelength tuning properties of strained InGaAs quantum well lasers using an external grating for feedback is reported. Tunable laser oscillation has been observed over a range of 170 nm, between 840 and 1010 nm, under pulsed current excitation.

High quality factors and room-temperature lasing in a modified single-defect photonic crystal cavity [PDF]

open access: yes, 2004
We propose and analyze a new photonic crystal cavity design that supports a dipole mode with a quality factor greater than 20,000. Such a high quality factor is obtained by precise tuning of the cavity length with minimal disruption of the surrounding ...

Wavelength tunable lasers in future optical communication systems [PDF]

open access: yes, 2008
Monolithic tunable lasers (TL) have been an important component in dense wavelength division multiplexed (DWDM) systems mainly because of their ability to reduce inventory costs associated with different part numbers for fixed wavelength distributed ...
