All-optical switches have attracted attention because they can potentially overcome the speed limitation of electric switches. However, ultrafast, energy-efficient all-optical switches have been challenging to realize owing to the intrinsically small opt
The realization of ultrafast integrated opto-optical switches with ultra-low switching energies remains an ongoing challenge. Broadband, silicon-compatible devices relying on gap plasmons and saturable absorption in graphene could pave the way forward.doi:10.1038/s41566-019-0571-7Viktoriia Rutckaia...

all-optical ultrafast modulation of the reflectance at a specific wavelength. Optical pumping of the system at its high energy ENZ mode leads to a strong redshift of the low energy mode because of the transient increase of the local dielectric function, which leads to a sub-3-ps control of...
In this Letter, we report for the first time to our knowledge that all-optical switching gain can be achieved with a dual-wavelength control versus pump beam scheme in a single semiconductor waveguide structure. That means a weak optical beam can switch a strong optical beam. Moreover, a hig...

We have reduced the switching energy for an all-optical soliton dragging NOR gate to 5.8 pJ by using a two-fiber configuration and optimizing the fiber and laser parameters. The cascadable NOR gate has a fanout of six, restores both the logic level and timing, and can operate at bit rates...
