Abstract

We report a successful experimental realization of a photonic-crystal Y splitter operating at λ~1.6 μm . Our device has a large splitting angle of 120° and a miniature size of ~3 μm×3 μm . Furthermore, the Y-splitter loss is measured to be 0.5–1 dB at λ=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.
