摘要：

We report a successful experimental realization of a photonic-crystal Y splitter operating at lambda similar to 1.6 mum. Our device has a large splitting angle of 120degrees and a miniature size of similar to3 mum x 3 mum. Furthermore, the Y-splitter loss is measured to be 0.5-1 dB at lambda = 1640-1680 nm, making the Y splitter promising for integrated photonic-circuit applications. These unique properties are attributed to the new guiding principle made possible by the photonic bandgap. (C) 2002 Optical Society of America.
