The establishment and relaxation processes of the transient gratings, which are formed by two recording 514nm beams with different polarization directions, SS, PP, SP and ±45℃, are investigated. Using the weak absorption of the chromophores at 632. 8nm and the positive dichroism of the chromophores molecules, a kind of bi-photonic transient gratings, owing to the periodic distribution of Trans and Cis isomers, is established first time in azo-dye doped polymeric bulk sample.

So chirped fiber gratings have broad reflection bandwidth. The group delay in chirped fiber grating reflection bandwidth changes gradually. These properties are what other type fiber gratings do not have.

所以chirped光纖光柵具有寬的反射帶寬亚洲另类图区，在反射帶寬內(nèi)具有漸變的群時延等其它類型的光纖光柵所不具備的特點。

Holographic concave gratings with three stigmatic points can be implemented through considerable design. Results obtained from holographic gratings can also be applied to ruled gratings. Sphere and coma aberrations for a planar concave grating are achieved through power expansions.

A stabilised optical fiber interferometric measurement system made with a 3×3 coupler and fiber Bragg gratings is presented. By employing the fiber Bragg gratings as in-fiber reflective mirrors, the system interleaves two fiber Michelson interferometers together that share the common-interferometric-optical path.

This kind of gratings can be kept in the material for a long time. A mode of molecular reorientation was used to explain the formation mechanism of these gratings and it is well consistent with our experimental results. 3. Three kinds of azobenzene polymers P , P (MMA-co-GY7) and P (MMA-co-GO13) were synthesized by radical polymerization. High-density optical storage and the three-dimension (3D) microstructures in the azobenzene polymer films were presented. Twenty gratings have been stored on the same spot in our material. It is twice as many as the best recording that has been reported. It is the first time, a rectangular microstructure and a complicated double layers nesting six-pointed star microstructure are inscribed in it by using a simple two-wave couple setup.
