All Optical Switching Using Optical Fibers and Nonlinear Organic Liquids.

摘要

Nonlinear optical organic liquids based on 2-methyl-4 nitroaniline (MNA)-type molecule in solution are potentially practical as third-order materials, featuring a large and fast intensity dependent index of refraction (n2), low optical loss insusceptibility to laser damage and a freely adjustable refractive index. The latter property makes them compatible with glass substrate devices and permits ease of fabrication for demonstration devices. Concepts and preliminary data are presented for a high speed all optical switch based on glass wave guides suspending a nonlinear liquid cladding of index matched organic solutions. (rh)
