Abstract
We report a successful experimental realization of a photonic-crystal Y splitter operating at . Our device has a large splitting angle of 120° and a miniature size of . Furthermore, the Y-splitter loss is measured to be 0.5–1 dB at , 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.
