New paper in Optical Engineering, with a q-plate operating at the 1550 nm telecom wavelength
We published a new paper in Optical Engineering Letters, entitled Generation of vector beams at 1550 nm telecommunications wavelength using a segmented q-plate. The paper appeared published in the third issue of OE journal in 2016.
In this work we present the use of a q-plate device operating at the 1550Â nm telecommunications wavelength. A prototype liquid-crystal device from Citizen Holdings Co. is demonstrated to be useful for the generation of vector beams and orbital angular momentum transfer at this important wavelength.
The device was developed for a visible wavelength, but we show here that it can be applied also for the 1550 nm wavelength, where is of interest to apply such devices to multiplex data with OAM channels.
This work was initiated during the stay of MarÃa M. Sanchez-López and Ignacio Moreno at SDSU during Summer 2015.
