Abstract
A Multichannel Fiber Optic Rotary Joint (FORJ) has a Dove prism as a derotating optical element, wherein the Dove prism has a multiwavelength achromatic metasurface coating on the input and output face. Such a Multichannel FORJ has the advantage that its transmission properties include consistently low attenuation over a rotation angle and a high-return loss over a broad wavelength range, e.g. the whole frequency band used for telecommunications. A method for fabricating the same.
