Abstract
Disclosed are a low refractive index resin composition for TPP nano 3D printing and photonic wire bonding method using the same. The low refractive index resin composition for TPP nano 3D printing is made of a fluorinated resin composition with a low refractive index including a (meth)acrylic reactive group with sufficient solvency for a photoinitiator for TPP reaction. As a result, by supporting to print a micro-sized single-mode optical waveguide as well as cladding of an optical waveguide surrounding the single-mode optical waveguide thus formed through a TPP nano 3D printing method, a photonic wire bonding (PWB) method that can manufacture a photonic integrated circuit (PIC) with minimal optical loss and high reliability is proposed.
