Pulse-shaping assisted nonlinear optical signal generation in fibres

, 2013
This thesis investigates pulse-shaping assisted nonlinear optical signal generation in fibers. A linear pulse shaping stage is included in nonlinear fibre optic systems to achieve flexible and precise control over the characteristics of the output signal.

Nonlinear Optical Properties of Tellurene Nanosheets for Harmonic Soliton Operations in an Er-Doped Fiber Laser

Photonics
Tellurene has a wide bandwidth and low propagation loss at near-infrared wavelengths due to its nonlinear absorption coefficient. Therefore, we prepared tellurene–polyvinyl alcohol (Te-PVA) film as a saturable absorber in an Er-doped fiber laser by ...

Mode-locked fiber laser using an SU8/SWCNT saturable absorber [PDF]

, 2011
We report the fabrication of a saturable absorber based on SU8 single wall carbon nanotube (SWCNT) composite material. Thin films with a controllable thickness can be fabricated using a simple and reliable process. These films can be inserted between two
