In this design an optical ring resonator are embedded between two Horizontal input and output waveguides which has 4 orbitals around the center of the resonator so that each orbital consists of 8 rods with different size in which radius of larger orbitals rods are bigger than radius of smaller orbitals rods. The analysis of simulation results showed the proposed filter has the transmission effi...

Strong atmospheric turbulence (disturbance due to rain, fog, haze etc.) is a major problem in optical communication system. In this paper, the performance analysis of an optical communication system with Free Space Optics (FSO), Optical Wireless Communication (OWC) and Single Mode Fiber (SMF) in weak atmospheric turbulence has been analysed. Data stream is transmitted at 20Gbps using different ...

In this paper, we propose an Adaptive Hybrid Transmission schemes for free space optical communication. Proposed algorithm utilizes hybrid mechanism which combines Multi-channel multicasting and unicast scheme to enhance not only service over service blocking probability but also reduce overall bandwidth consumption of the free space optical communication system which has very limited resources...

Abstract: In this paper, we aim to design and propose a novel structure for all-opticalhalf subtractor based on the photonic crystal. The structure includes two optical switches,one power splitter, and one power combiner. The optical switches are made of theresonant rings which use the nonlinear rods for dropping operation. The footprint of thedesigned structure is about...

While the application of optical and photonic technologies in the communications, computing, medicine and industrial manufacturing has been growing rapidly, the miniaturization of these technologies has been slow due to the limitation on the diffraction. However, the developments of nanoscale components and guiding methods are continuing with a rapid pace. Since waveguiding is a fundamental iss...
