We have recently developed a simple fabrication technique, called low one-photon absorption (LOPA) direct laser writing (DLW), to realize multi-dimensional and multi-functional polymer-based photonic submicrostructures. This technique employs a continuous-wave laser at 532 nm-wavelength with only few milliwatts and a simple optical setup, allowing to decrease the cost of the fabrication system by a factor of ten as compared to a commercial DLW system. In this report, we present various photonic structures, such as 2D and 3D micro- resonators, photonic and magnetic submicrostructures, and nonlinear optical structures fabricated by this LOPA- based DLW method. We also discuss about potential applications of those fabricated multi-dimensional and multi-functional photonic submicrostructures in opto-electronics, bio, as well as in opto-mechanics.
