Abstract
We report an experimental study on optical and magneto-optical properties of Cesubstituted yttrium iron garnet thin films incorporating gold nanoparticles. Au nanoparticles were formed by heating Au thin film on cubic quartz and garnet substrate in vacuum chamber and a Ce:YIG layer was deposited on them by the aid of Pulsed laser deposition method. A large enhancement of the longitudinal Kerr effect was obtained in sample with Au nanoparticles on quartz substrate and the effect of substrate material on improving optical and magneto-optical response of samples were investigated.

Abstract
In this paper, we proposed an all optical 4-to-2 encoder that has 4 input and 3 output ports. This device generates a 2 bit binary code based on which input port is active. We used nonlinear photonic crystal ring resonators along with optical power splitter for realizing the proposed encoder. In this device the switching rate and area are obtained about 333 GHz and 612µm2 respectively.
