用光致聚合物全息干版实现光互连

Realization of Optical Inteconnection on the Holographic Plate of the Red Sensitive Photopolymer

用全息术在光致聚合物全息于版上制备出全息耦合光栅。将光信号耦合进玻璃光导板中，使其在光导板中全反射，以锯齿形式传播。再经出射光栅耦合出来。在光导板上实现１点对１点的光互连，互连效率约为２５％。

Holographic coupling gratings have been frabricaed on the Red SensitivePhotopolymer(RSP) holographic plate with holographic technology.Optical signal iscoupled along the total internal reflection anSle inside the light-guiding plate and coupled outby the coupling gratings.The one by one point optical interconnections has been realized, itscoupling efficiency is 25 %.
