Dual-wavelength signals delays via Brillouin Slow Light in an Optical Fiber

We demonstrate the single and dual wavelength signals delays visa Brillouin slow light in the single mode fiber at the same time. Moreover, each wavelength delay of the signal can be also controlled by the other wavelength pump power. For single wavelength, the width of 100ns pulse can be delayed from 0ns to 40ns by tuning the power of the pump while for dual wavelengths pump the delay time decrease to 30ns.
