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 ...

Passive Optical Networks

The optical access is gaining more interest as the demand for higher and higher bandwidth is getting stronger. The major drivers for larger bandwidth are the increasing processing power of user terminals and development of services that require substantially larger bandwidth than available in present day access networks. The prevailing access techniques, such as the digital subscribes line syst...

Window - Based Permit Distribution Scheme for ATM Passive Optical Network ∗

Recent progress in the optical transmission technology makes an ATM passive optical network (APON) a good candidate for access networks. APON based on tree topology requires efficient medium access control (MAC) to multiplex upstream data flows efficiently while not disturbing the original pattern. In this paper, we proposed a Window-based permit distribution scheme for the MAC protocol of APON...
