Although lightwave technology is meeting the demand for point-to-point and long-haul transport of digital information, routing packets at the nodes of the network has typically been carried out using electronically switched backplane routers. The growing capacity on the Internet is placing an ever greater demand on electronic routing technologies. While WDM can support large aggregate traffic b...

In this paper present that it is possible to control the characteristics of spin waves (SW) in a system lateral magnetic waveguides made iron yttrium garnet (YIG) by changing antiferromagnetic iron-rhodium (FeRh) layer located above these waveguides. particular shown geometric parameters and magnetization FeRh one can amplitude phase SW propagating microwaveguides. The modes under which dips ap...

In an expansion of a previous study [1], we apply inverse design methods to produce two-dimensional plasma metamaterial devices with realistic elements which incorporate quartz envelopes, collisionality (loss), non-uniform density profiles, and resistance experimental error/perturbation. Backpropagated finite difference frequency domain simulations are used waveguides demultiplexers operating u...

Mode multiplexers/demultiplexers (MUX/deMUX) are key components in mode division multiplexing. A silica waveguide MUX consisting of four cascaded directional couplers is experimentally demonstrated. The beam propagation method used the device design and optimization. Thermal oxidation, plasma-enhanced chemical vapor deposition, ultraviolet photolithography adopted fabrication. measurement resul...

Optical circulators are used in optical devices such as multiplexers, demultiplexers, and routers. Usually, the magnetic material center of circulator conducts light by interacting with electromagnetic wave. In this research, a polarization-independent four-port waveguide presence rhombus-shaped ferrimagnetic has been designed, simulated, optimized three-dimensional part Comsol software. This d...

An optical soliton pulse may be used as a control signal in non-linear optical loop mirror demultiplexers in order to reduce timing-jitter noise and cross-talk. A mathematical model for calculating the width of the soliton switching window and optimizing critical parameters such as walk-off time and pulse width has been presented, and its accuracy is verified by solving the nonlinear Schrodinge...
