Abstract
A holographic optical data storage device according to the present invention includes a photopolymer layer having an upper surface and an oppositely disposed lower surface. The device includes a substantially transparent upper substrate layer having a first inside surface lying adjacent to the upper surface of the photopolymer layer. The device includes a substantially transparent lower substrate layer having a second inside surface lying adjacent to the lower surface of the photopolymer layer. The upper and lower substrates have first and second peripheral edges respectively with an opening formed therebetween. The device further includes a connection member engaged to the upper and lower substrates wherein the connection member seals the opening. A method of fabricating a holographic optical data storage device is also provided.
