Ultrahigh transmission optical nanofibers

Supermodes for optical transmission.

In this paper, the concept of supermode is introduced for long-distance optical transmission systems. The supermodes exploit coupling between the cores of a multi-core fiber, in which the core-to-core distance is much shorter than that in conventional multi-core fiber. The use of supermodes leads to a larger mode effective area and higher mode density than the conventional multi-core fiber. Thr...

Optical Theorem for Transmission Lines

We present the application to transmission line systems of a new theory of the optical theorem that describes the energy budget of electromagnetic scattering in lossless wave propagation media. The insight gained by exploring this, simplest of the electromagnetic wave propagation systems from the point of view of the optical theorem, is important for understanding power budget of electromagneti...

Simulation and Analysis the Performance of 3970 Km DWDM Transmission Link Employing Optimized Semiconductor Optical Amplifiers

In this paper first we try to analysis the behavior ofthe SOAs in the optical networks and then have proposed anumerical simple model to simulate the behavior of thesemiconductor optical amplifiers. After that by employing thismodel as inline amplifier for a DWDM optical system, we havesimulated the transmission of 10 channels with bit rate 10 Gb/sup to distance 3970 km with RZ-DPSK modulation ...
