We generate, for the first time and to the best of our knowledge, a tunable ultra-flat optical frequency comb (OFC) block from a 10-GHz bismuth-based actively mode-locked fiber laser. A bismuth-based erbium-doped fiber (Bi-EDF) with a length of 1.5 m

We propose novel methodology to identify and localize soft-failures using performance metrics monitored at repeater nodes in addition to signal quality monitored at transponders and show feasibility in experiments using commercial equipment and field

Recently, there has appeared an attractive candidate for the all-optical switches, which employs the cascaded χ (2) effect in quasi-phase-matched (QPM) LiNbO 3 (LN) waveguides [1] - [4] . In these switches, when the center wavelength of the clock is

We report selective and tunable wavelength converters (STWCs) from an arbitrary wavelength to another arbitrary one, which employ the cascaded second-order nonlinear effect of sum frequency mixing (SFM) and difference frequency mixing (DFM) in quasi-

Characteristics of an all-optical switch employing a 3-cm-long quasi-phase-matched lithium niobate are investigated through switching experiments considering the temporal widths of the input clock and signal pulses. Stable and efficient 40-GHz operat
