In this paper, we present a deep learning-based Device-to-Device (D2D) approach that utilizes Gated Recurrent Unit (GRU) model is optimized through Bayesian optimization for hyperparameter tuning. The proposed approach, DLCE-D2D (Deep Learning Cache-Enabled device-to-device) system learning using GRU, to predict the popularity of content in D2D network and dynamically adjusts cache eviction pol...

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.
