  Recently, two special photonic jets, photonic hooks and twin photonic jets,
have been proposed to deal with complex conditions in nanoscale manipulation.
Photonic hooks are generated by a single light plane wave and an asymmetric
microparticle, while the twin photonic jets are produced by two incident light
beams. In this letter, we presented and demonstrate a method to combine
photonic hooks and twin photonic jets. A single light plane wave and a
symmetric microparticle, twin-ellipse microcylinder, are used in this research.
The curvature degree, length and maximum E2 filed enhancement of twin photonic
hooks are varied significantly, with the change of refractive indices and shape
of twin-ellipse microcylinder. And a liquid-immersed core-shell is built to
achieve a flexible tunability.
