Variable optical power splitter based on slot waveguide

To meet the application demand of optical communication system, a new type of variable optical power splitter (VOPS) based on slot waveguide by adjusting manually is proposed in this paper. The device is designed by using the principle of optical field effect. It has an import port which provides import power, and two output ports, the power of which is divided dynamically by changing the width of the gap between two slot waveguides. This paper can specify the operation principle of the device, test its important technical indicators and analyze experimental datum. Experimental results show that the device can realize light distribution of the single wavelength and multiple wavelengths and that the power splitting ratio is dynamically tunable and the tuning range can be 1–25dB, which ensures rapid organization and deployment of communication network.
