We demonstrate a 10-GHz multiwavelength pulsed generator based on a fiber optical parametric oscillator. By introducing two separated intracavity branches, simultaneous mode-locking at two different wavelengths in the L-band is achieved. Due to the parametric process between the pump and the two mode-locked signals, two idlers are generated in the S-band. Hence, simultaneous generation of a 10-GHz...
We experimentally demonstrate simultaneous demultiplexing of 80-Gb/s OTDM signal by transforming it into WDM idlers (spaced by 1.15 nm), based on a swept-pump fiber-optical parametric amplifier (FOPA), and ∼10-dB parametric gain is achieved.
The optimized parameters of wavelength exchange vary from fiber to fiber due to zero-dispersion wavelength fluctuation. This problem can be solved by reducing wavelength separation between signal and idler at the expense of reduced tunability.
Single-longitudinal-mode fiber optical parametric oscillator is realized by resonating independently the signal and idler frequencies in two separate optical cavities, combined with a sub-ring cavity inserted into the signal cavity.
