Although a fiber coupler is widely used in application and numerous methods have been researched, several phenomena still occur in the optical fiber, where power in fiber couplers not only depends on the waveguides, but also the power parameters. A matrix transfer method is used to model phenomena for several junctions. An optical switch, the fabricated fusion directional coupler, enables the routing of optical data signals without the need for conversion to electrical signal, independent of data rate and protocol. Therefore, an applied voltage is designed to control and drive parametric...

Over the past two decades, a mechanism process to obtain Single Mode Fiber (SMF) coupling has emerged as a visible means for fiber optic communication. Generally, the process is always described at initial input and output result, whereas the source waves transmitting along the coupled fibers have not been fully understood. Although modeling of fiber coupling provides good understanding of the process, but experimentally the determination of the coupling range has not been clearly established. In applications optical fiber coupling is used to control and to apply power propagation from one...

The formation and characterization of CdS nanoparticles embedded within Langmuir-Blodgett films are described. CdS nanoparticles were formed within calyx arene (CA) and stearic acid (SA) Cd-salt LB films by exposure to H2S gas at room temperature. The AFM images of the treated SA and CA bilayers show CdS clusters with lateral dimensions. These particles are pseudo two-dimensional and have a shape of hexagonal platelets. The transformations of the absorption spectra by ageing yield a monotonic increase in CdS cluster size with the tendency of saturation. This behaviour is modeled with two...

Fiber coupler is a great utilization to combine and to split one or more optical power input and outputs. Power transfer in fiber coupler depends on the geometry of the waveguides and the coupling coefficient. Power transfers between the waveguides are calculated using matrix transfer method. By introducing power input to the one of the waveguides, assuming cross section, power propagation, and fiber axis are held constants at coupling constant coupling coefficient, it shows that coupling length of NX2, linear order NX3, and triangular NX3 fiber couplers are odd-multiple of z= /(2 ), z= /((...
