Customized fiber generates Bessel beams

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications.

Chiral sources for metamaterial interface waveguides

Metamaterial interface waveguides can confine and guide electromagnetic (EM) waves, which has attractive potential in integrated photonics physics and wireless devices, from radio frequencies to optical bands. The energy ...

Review discusses using nonlinear optics with structured light

Light can be tailored, much like cloth, weaving and stitching a pattern into the very fabric of light itself. This so-called structured light allows us to access, harness and exploit all light's degrees of freedom, for seeing ...

Physicists discover special transverse sound wave

Can you imagine sound traveling in the same way as light does? A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: The airborne sound wave vibrates transversely and carries both ...

Three-dimensionally oriented orbital angular momentum of light

Recently, National Science Review published online the research results on three-dimensionally oriented orbital angular momentum of light from Professor Qiwen Zhan's team at the University of Shanghai for Science and Technology.
