Passive optical nonlinear module for spectral shifting of solitons, 1550-2100 nm

Nonlinear optical fiber modules for spectral shifting of femtosecond solitons utilize the phenomenon of soliton self-frequency shift (SSFS). They allow wavelength tuning of femtosecond lasers in the near-infrared range. Typically, a soliton from a fixed wavelength erbium femtosecond source can be tuned from the 1550 nm range up to 2100 nm wavelength. The output wavelength is easily tuned by changing the input optical power. Wavelength-shifted output signal maintains coherence and linear polarization. The modules are fully plug&play. They are passive and require only connecting to the laser source output port.
