Abstract
Previously, microdisks were fabricated using a subtractive method such as the proton beam writing method [1] or lithography [2-4]. These subtractive methods are suitable for mass fabrication in large areas. However, subtractive methods are not suitable for single on-demand fabrication due to unnecessary waste materials and large energy consumption. Moreover, it is challenging to conduct all processes on demand or under room-temperature (RT) atmospheric conditions. Recently, we proposed an ink-jet printing method for single fabrication. It is very superior at producing low waste materials, requires little energy consumption, and is suitable for on-site fabrication because it is an additive method. In order to handle a high-concentration solution for the waveguiding condition of micrometre-order thickness, it is important that hyperbranched polymers are used in the ink-jet technique. The viscosity of hyperbranched polymers is much lower than that of general linear polymers in solvents.
