Individual Behaviors

Kinetic and optical behaviors of Cibacron™ Yellow R, Scarlet 2GE, and Blue TRE are studied individually and in mixtures. In mixtures, these dyes deviate from their individual behaviors. A method for determining these deviations and for correlating the optical and kinetic deviations is demonstrated. This method is valuable because it allows the kinetic behavior of dyes in mixtures to be characterized from simple optical measurements.

Tem Characterization

An optical waveguide consists of a several-micron wide channel with a slightly different index of refraction than the host substrate; light can be trapped in the channel by total internal reflection.Optical waveguides can be formed from single-crystal LiNbO3 using the proton exhange technique. In this technique, polished specimens are masked with polycrystal1ine chromium in such a way as to leave 3-13 μm wide channels. These are held in benzoic acid at 249°C for 5 minutes allowing protons to exchange for lithium ions within the channels causing an increase in the refractive index of the channel and creating the waveguide. Unfortunately, optical measurements often reveal a loss in waveguiding ability up to several weeks after exchange.
