All-optical Ultrafast Switching Based on Plasmon-generated Hot Carriers in Gold-coated Fiber Gratings

Not Accessible

Your library or personal account may give you access

Abstract

Pump-probe modulation of 4.95% is observed experimentally and by simulations in gold-coated tilted fiber Bragg gratings at power densities of 205 MW/cm2 with 25 ps pulses from a tunable laser at wavelengths near 1550 nm.
