Abstract
Minimizing the waveguide is very important in optical communications as the semiconductor components become smaller and smaller, but the fabrication of low-loss optical waveguides with sub-wavelength diameters remains challenging. In this work, we utilized an improved drawing tower to obtain the silica micro/nano optical wires (MNOWs) with several micrometers or several hundred micrometers. The MNOWs had extremely good diameter uniformity with long length up to tens of centimeters, and they were properly handled with a tungsten needle. The tip of a fiber taper could be attached to a guiding silica wire because of van der Waals attraction between the two, and the power was launched into these wires by evanescent wave. Also, the wires had an average optical loss of less than 1.0dB/mm. Furthermore, we successfully assembled the connection between a fiber taper and an MNOW by UV glue in air to simplify the package process. We used the waveguide simulation software to design the micro wavelength division multiplexer (MWDM) suitable for 980/1550nm light wave, and the MWDM had a high wavelength separation ratio.
