Abstract
The design, fabrication and evaluation of photonic crystals (PhC) have attached more and more interests in recent decades. In this paper, a homemade femtosecond laser microfabrication system is described. The optimization of working parameters, especially for resolution power or 2-photon microfabrication and the spatial overlap ratio of scanning, is presented. After that, several log-pile type PhCs are made through 2-photon induced photopolymerization. And their reflection spectrums are got with an infrared spectrometer equipped with an infrared microscope. For comparison, simulation result of photonic bandgap (PBG) using a plane-wave based transfer-matrix method is shown. The measured reflection spectrum of our PhC is agreed with the simulation one quite well.
