Autocloning is a method for fabricating multi-dimensional structures by stacking the corrugated films while keeping the shape. Its productivity, robustness against perturbation, and flexibility regarding materials and lattice types make autocloning suitable for mass production of photonic crystals. Therefore we aim to industrialize autocloned photonic crystals. Recently, we are starting to market polarization beam splitters for optical telecommunication by using 2D photonic crystals, and are developing some devices using the splitters, such as isolators or beam combiners. The applications of the splitters are also extending to multi-section type of devices and to visible range devices. Meanwhile, development of optical integrated circuits by utilizing autocloned photonic crystals is in progress. Low loss propagation and some functions have been demonstrated.
