We report a strategy of industrialization of photonic-crystal based optical devices: We first review requirements for passive photonic crystal components. Although they have remarkable properties, they have at the same time severe difficulties such as difficulty of practical coupling to/from optical fibers and a relatively large propagation loss. This paper present an approach of meeting the requirements using heterostructured photonic crystals fabricated by autocloning. A low-loss, simple structured waveguide and sophisticated functional blocks (such as a resonator) can be integrated by a simple process. We first prepare a substrate patterned and corrugated by electron beam lithography and dry etching. Ta2O5/SiO2 mutilayers are repeatedly deposited on the substrate, and no other process is needed to complete the chip. After dicing and polishing, the waveguide can be butt-jointed with an optical fiber and the loss is estimated as 1.3 dB/mm. A resonator with Q = 270 is also demonstrated. Furore outlooks of the technology are also discussed.
