Abstract

In recent decades, research in the field of optoelectronics has attracted great interest. Modulators are one of the most usable optical components in the optical communication systems. The most important parameters for a modulator are high modulation speed, small footprint, and large optical bandwidth. In this paper we design and fabricate an all-optical intensity modulator based on optical microfiber in which graphene oxide replaces the clad of microfiber. We chemically etched the clad of multimode optical fiber. Then we coated aqueous solution of graphene oxide with concentration 5 mg/ml on the microfiber that has 90° curvature. The graphene oxide was irradiated directly by the pump laser (power=500 mW) at wavelength 405 nm from outside the microfiber. We were able to achieve a maximum modulation depth of 27.3% by graphene oxide. The modulator has been built has many advantages such as compatibility with optical communications, easy fabrication, and low cost.
