"Ellipsometric Measurements of the Electro-Optic Coefficient"
Faculty Mentor: Dr. Michael Hayden
Expected Graduation Date: Spring 2009

A device will be fabricated that will be used in an experiment crucial to the non-linear optics research group here at UMBC. The aim of building the device is to enable the group with the ability to get more precise measurements of the Electro-optic (EO) coefficient, r33, of polymers used in Tera-Hertz generation. The aim of the research involved with building the device is to explore the possibility of diminishing the amount of error present in the current method. Meanwhile, a lasting understanding of EO coefficient measurement will be developed, and recorded in a user manual to aid future undergraduate research assistants in understanding the physics behind the measurement. The project was chosen in order to provide the group with a means of recording publication quality measurements of the EO coefficient. In effect, this device will save the group from trips to the labs of similar research groups to make the measurements. Upon completion of the project, the research group will have a new apparatus to teach new undergraduate researchers with and a responsible device for recording the EO coefficient with publication quality precision.
