TL;DR: For the first time, it is experimentally demonstrated that the lower limitation of the operation bandwidth does exist and differentiators with different bandwidths have significantly different acceptable pulse width range of input signals, which is consistent to the theoretical prediction.

TL;DR: By introducing laser oscillation in erbium-doped fiber amplifiers, the four-wave mixing effect is successfully suppressed and improvement of the amplifier performance is achieved as mentioned in this paper, which implies that this suggested approach can be applied in the practical dense wavelength-division multiplexing systems to minimize channel crosstalk.

TL;DR: In this article, the authors theoretically demonstrate the multibistability and multistability features of two coupled active microrings using the continuation method to solve the parametric nonlinear equations of these two-active-microring systems.

TL;DR: In this article, the first experimental demonstration on 40 Gbit/s all-optical format conversion from NRZ to CSRZ, from RZ to RZ, and from NNRZ-DPSK-to RZ-DSK using a periodically poled lithium niobate (PPLN) waveguide was reported.

TL;DR: All-optical logic gates based on semiconductor optical amplifiers and tunable filters and SOAs with advantages such as powerful function, flexible operational principle and possible integrated could help these schemes to have potential applications in optical computing and optical networks.
