Spiral spectrum separation for information transmission by using orbital angular momentum of light beam

Not Accessible

Abstract

Orbital angular momentum (OAM) can be used in information transmission since OAM states can construct high dimensional Hilbert space. We propose a method to separate such OAM states quantitatively, i.e. spiral spectrum, according to the Rotational Doppler Effect (RDE).
