摘要：the geometry effect of the structure is put in profile during the survey of an important criteria of these fibers namely the confinement loss. To optimize an optical fiber structure constituted with a doped core, the value of confinement loss must be as low as possible; a new structure is introduced in our analysis. It is a structure formed by a doped core surrounded by a cladding which is composed by a photonic air holes in silica. These holes have an elliptic shape which is present some angular orientation. The first air ring around the core is oriented in a way that reduces the confinement loss values. The introduction of liquid with various values of refractive index in the elliptic holes still reduces the values of the confinement loss. The study of such a structure leads us to the study of Maxwell's equations therefore a numerical method is required, we chose the Finite Difference Time Domain method (FDTD) with transparent boundary condition (TBC).
