New paper in OSA Continuum about double ring interference with binary axicons
A new paper is available at OSA Continuum entitled Double-ring interference of binary diffractive axicons.
Here we report on the interference between the double rings generated by the Fourier transform of a binary diffractive axicon. These two rings have the same size and correspond to the +1 and -1 diffracted order beams. The interference condition between both rings can be easily changed by adding a constant phase bias. Additionally, this interference condition can be changed along the ring.
This work has been done in collaboration with our colleagues at San Diego State University Prof. Jeffrey A. Davis, Prof. Don M. Cottrell and Benjamin Gutierrez.
