A heterostructured photonic-crystal functional chip consisting of a resonator and waveguides is fabricated by a simple "autocloning" process. First, we prepare a substrate with different corrugation patterns by electron beam lithography and dry etching, and Ta2O5-SiO2 multilayers are successively formed upon the substrate. An in-line resonator is fabricated and characterized by fiber-in-fiber-out measurement, and a resonance peak with Q = 270 is demonstrated. The future outlook for the technology is also discussed.
