Abstract

This paper summarizes our recent progress on using 3D printing and laser micromachining methods to fabricate optical microsensors for various applications. Optical grade glasses are printed by 3D extrusion and laser sintering. High-precision and high surface quality optical structures of arbitrary shapes are obtained by ultrafast laser micromachining and CO2 laser resurfacing. Combining these advanced manufacturing methods, various optical structures and components can be made with flexible shape and desired accuracy. With unique advantages such as compact size, high thermal stability, and integrated optical functions, these 3D printed structures can be used as sensors for many applications.
