In this project, we want to measure the DDMEBT-polymer nonlinear optical properties by using the z-scan technique.
An empirical rule, called Miller’s rule, suggests that the nonlinear optical properties of any material increase with its own index of refraction. However, for certain efficient waveguide-based devices, this is not ideal; a material with high nonlinearities and low refractive index, the opposite of Miller’s rule, is sought. A few years ago a new organic film was created, exhibiting exactly these characteristics, called DDMEBT, which is very difficult to manufacture. One of our collaborators in Tokyo has synthesized the polymeric version of this material, way easier to and handle. However, our z-scan currently is not performing as expected. We think that it requires the installation of a reference arm which will reduce enormously the background generated by the laser fluctuations. Hence, we need to install and test the reference arm and demonstrate the expected performance. At this point, we would be able to measure the new material nonlinear optical properties.
