Experimental Demonstration of Optical Fast Frequency Hopping-CDMA Communications

Code division multiple access (CDMA) is a highly flexible multiple access protocol, however, significant signal bandwidth expansion is required. Given the Terahertz pass band of optical fiber, the frequency spreading of the CDMA signal is no impediment, provided it can be accomplished optically. Among wide variants of optical CDMA techniques, only a spectral encoding based approach [1] has pene...

Novel Four-Channel All Optical Demultiplexer Based on Square PhCRR for Using WDM Applications

Ring resonators have always been referred to as a highly flexible structurefor designing optical devices. In this study, we have designed and simulation a fourchannel optical demultiplexer using square photonic crystal ring resonator. The squarelattice constant for this purpose structure is used. The purposed structure has an averagecrosstalk, transmission coefficient, q...

Anti-Jamming Frequency Hopping Techniques for Secure Multicast Communications

We address the problem of jamming mitigation of multicast communications in multi-channel ad hoc networks. Specifically, we develop two frequency hopping (FH) techniques for establishing multicast communications. These techniques, denoted by KFH and CFH, address the two following problems. First, establishing multicast communications in the presence of a control-channel jamming attack. Second, ...

Improvement of Optical Properties in Hexagonal Index-guiding Photonic Crystal Fiber for Optical Communications

Waveguides with low confinement loss, low chromatic dispersion, and low nonlinear effects are used in optical communication systems. Optical fibers can also be employed in such systems. Besides optical fibers, photonic crystal fibers are also highly suitable transmission media for optical communication systems. In this paper, we introduce two new designs of index-guiding photonic crystal fiber ...
