Anthony S Kewitsch, George A Rakuljic, Doruk Engin, Seth J Greenberg, Phil A Willems, Xiaolin Tong: Methods of fabricating grating assisted coupler devices. Arroyo Optics, Jones Tullar & Cooper P C, January 2, 2001: US06169830 (23 worldwide citation)

Advantageous methodologies are disclosed for embedding periodic patterns in optical waveguide elements such as optical fibers. Polarization independence in an elongated waist region of an add/drop coupler can be established by measuring polarization characteristics during fusion and elongation, and ...
