The presented work here is focused mainly on the study of physic-chemical changes of organic material by
the electron -beam direct- writing technique. The organic polymer studied here is (diethyene glycol bis
(allycarbonate)) called CR39. The most
important changes that we will focus on are the depth of
penetration of the electronic beam as a function of the energy of electrons. This penetration will lead to an
increase in the refractive index of this material, which can allow the formation of components and
integrated optical circuits to be used in optical communications.
The first phase of this work will allow us to study the physico-chemical changes in organic material under
effect of low energy of electronc beams which are the domain of our interest (from 5 keV to 25 keV),
corresponding to the possibility of forming optical structures with very small dimensions and without the
need to mask technology which is used by ion beams, and these structures can be used in optical
communications.
Therefore, in the second phase of this study, we will make use of these changes and we will verify the
possibility of acquiring guided electromagnetic propagation through a structure of identical dimensions to
the employed electronic energy.
This structure can constitute the main element in formulating integrated optical circuits: such as Bragg
grating, Optical filters.
