Beschreibung
Zusammenfassung:	Electrically controlled volume phase gratings and electrically controlled Bragg Gratings can provide variable diffraction gratings that can be operated in a transmissive and/or reflective mode. They can be made from electro-optic materials placed directly on glass or semiconductor materials, utilizing conventional Liquid Crystal on Silicon (LCOS) processes and equipment. Highly efficient and/or small device form factors may be provided.
