23 March 2005 Tunable femtosecond soliton generation in a Ge-doped fiber
Author Affiliations +
In contrast with conventional polarization maintaining fibers, a simple Ge-doped single-mode fiber is used to generate tunable femtosecond soliton pulses. Soliton self-wavelength-shift up to 200 nm is achieved in a 17 m long fiber. The generated “monocolored” soliton pulses have quasi-ideal sech spectral shapes. A high contrast optical switching scheme is proposed as an example of potential application of the soliton self-frequency shift.
