Summary: | Recently, the rapid growth in photonic field has increased the demand for nonlinear materials with higher
performance and greater efficiency. Hence, a thorough investigation on the nonlinear optical properties of
materials are essential and need to be done for possible future application of the material in photonic field as
optical limiting or optical switching devices. Thus, through this research, the crucial parameters in nonlinear
optical properties of zinc borotellurite glasses doped with lanthanum oxide and lanthanum nanoparticles were
studied and investigated extensively. The two series of glasses were successfully fabricated via conventional
melt-quenching technique. The fabricated samples were characterized by using Fourier Transform Infra-Red
(FTIR) spectroscopy as well as Z-scan technique in order to study the structural and nonlinear optical properties
of the glass systems. The existence of various amount of TeO4, TeO3, BO4 and BO3 in all the prepared glasses are
proven through the observable absorption bands in the FTIR spectra. Inconsistent trends recorded for both
nonlinear absorption coefficient and nonlinear refractive index might be associated with the simultaneous
creation of bridging as well as nonbridging oxygen which eventually affect the values for both parameters. The
figure of merit of the prepared glasses with values ranging from 0.055 to 0.267 which are smaller than one hints
that the glass materials possess potential to be employed as all optical devices. 0.03 M fraction of lanthanum
nanoparticles doped zinc borotellurite with FOM value larger than 1 has proven the ability of the respective glass
to be employed as efficient all optical switching devices. The determined nonlinear optical parameters of the
glasses should be able to provide sufficient and useful information on the fabricated glass samples for future
application in photonic field. |
