Diffractive and micro-optics for wavefront manipulation

SPIE Proceedings, 2012
The exploitation of micro-optical technologies in laser beam shaping and wavefront manipulation applications has a long and distinguished history. The functional flexibility of high resolution, allglass phase only microstructures, combined with their relative immunity to laser-induced damage mechanisms, allows the creation of arbitrary beam profiles

Vanadium Dioxide Energy Selective Surface for Nonlinear Wavefront Manipulation

European Conference on Antennas and Propagation
A novel vanadium dioxide (VO2) energy selective surface was designed, fabricated, and tested for operation in X-band. VO2 is an insulator-metal-transition phase-change material that exhibits a sharp conductivity change at a temperature of 68°C or with a ...

Photonics on a fiber for wavefront manipulation

Advanced Fabrication Technologies for Micro/Nano Optics and Photonics XI, 2018
Fabricating photonic structures directly on the edge of an optical fiber opens opportunities in telecommunication, sensing, lab-on-fiber and as a replacement for the conventional free-space optics. The main advantages are long-term stability, compact size, ease of use, and the scalability.

Direct wavefront manipulating for a transverse electric wave microlens

Optics Letters, 2016
Due to the polarization nature of the transverse electric electromagnetic wave, manipulating it has been a difficult task and can be even more challenging for integrated on-chip optics. In this Letter, a transverse electric wave manipulating method based on direct wavefront bending and its physical picture have been proposed. Even with only five cells,

Wavefront manipulation in imaging: when blurry is better

Frontiers in Optics, 2003
Traditional imaging system design places a priority on correcting the exit pupil wavefront to produce a sharp image at the plane of detection. This paper discusses applications where system performance is improved by manipulating the wavefront to differ from a converging spherical wave.
