40 GHz Mode-Locked SOA Fiber Ring Laser with 20 nm Tuning Range
High repetition rate, picosecond laser sources are key elements for WDM/OTDM transmission, switching and photonic network systems. Active mode-locking is one of the main techniques for the generation of transform limited, high repetition rate, short pulse trains. It is particularly appropriate for applications that require precise timing synchronization between the optical and electrical signal...
متن کاملPassively mode-locked 10 GHz femtosecond Ti:sapphire laser.
We report a mode-locked Ti:sapphire femtosecond laser emitting 42 fs pulses at a 10 GHz repetition rate. When operated with a spectrally integrated average power greater than 1 W, the associated femtosecond laser frequency comb contains approximately 500 modes, each with power exceeding 1 mW. Spectral broadening in nonlinear microstructured fiber yields comb elements with individual powers grea...
متن کاملCarbon Nanotube Mode-Locked Thulium Fiber Laser With 200 nm Tuning Range
We demonstrated a mode-locked thulium/holmium (Tm/Ho) fiber laser continuously tunable across 200 nm (from 1860 nm to 2060 nm), which to the best of our knowledge represents the widest tuning range ever achieved for a passively mode-locked fiber laser oscillator. The combined use of a broadband carbon nanotube (CNT) saturable absorber and a diffraction grating mirror ensures ultra-broad tuning ...
متن کاملGeneration of 10 GHz pulse packets from an actively mode - locked fiber ring laser
Future ultra high-speed optical networks will probably rely on optical packet switching, where packets of high-speed data can be routed to any node in the network [l]. To allow packet generation at bit rates >40 Gbit/s, return to zero (U) data format will most likely be used which also allows the use of solitons in a transmission link. This will, however, require a very high quality pulse sourc...
متن کاملTuning extension of a Difference-Frequency generation up to 100 nm using V-shaped external-cavity for the pump laser
In this research, tunability of a commercial diode laser has extended to about more than ± 11 nm using a V-shaped external-cavity fabricated around the laser. Although under normal condition it can be tuned up to about ± 4 nm just by changing its temperature and injection current. Such modified diode laser has then used in a difference-frequency generation (DFG) experimental setup as pump sourc...
