Characterization of light-control-light system using graphene oxide coated optical waveguide
An optical waveguide was coated with graphene oxide (GO) using the drop-casting technique to
increase the interaction between the waveguide’s evanescent field and the GO layer. Subsequently, a
1550 nm tunable laser source and 980 nm pump laser is used to study the potential of the GO-film to
control the flow of light through the waveguide by altering the state of the waveguide between
transparent (ON) and opaque (OFF). The GO layer has a thickness of 0.40 µ m and allows a 1550 nm
signal with a peak power of −7.0 dBm and average output power of 0 dBm to pass through at a maximum
pump power of 60 mW. The waveguide has a responsivity of ~0.1 dB mW −1 , with the time to switch
between the ON and OFF states being about 3 ms.
