Abstract
A volume phase holographic grating includes two cover shields and a holographic optical member. The holographic optical member is created by taking gel and having two lasers interfere with each other on the gel such that a pattern is created on the gel. The optical member placed between the two cover shields such that the optical member is protected.
Claims5
A volume phase holographic grating comprising:
- two cover shields;
- and,
- an holographic optical member, the member created by taking gel and having two lasers interfere with each other on the gel such that a pattern is created on the gel;
- the optical member placed between the two cover shields such that the optical member is protected.

A volume phase holographic grating comprising:
- two cover shields;
- and,
- an holographic optical member, the member created by taking dichromatic gel and having two lasers interfere with each other on the dichromatic gel such that a pattern is created on the dichromatic gel;
- the optical member placed between the two cover shields such that the optical member is protected, the dichromated gel has an average refractive index of about 1.5 and a refractive index modulation of about 0.022.
