MEMS optical switch technology is one of the key technologies in Wavelength Division Multiplexing (WDM) optical networks. Although the 2-D MEMS optical switch technology is mature, the commonly used crossbar architecture is not amenable to building large switches. In this paper, we propose a design of 2 × 2 switching modules, and use it to build large 2-D MEMS optical switches with architecture...
In this contribution we develop a theoretical statistical approach to predict the acceptable bandwidth tolerances for optical filter cascades in wavelength division multiplexing (WDM) networks. We also establish tolerances for the center frequency misalignments considering a statistical approach presented in a previous work. The optical filters analyzed have a trapezoidal shape, and different b...

The techniques to implement radio over fiber (RoF) systems using optical subcarrier modulation (SCM) and dense wavelength division multiplexing (DWDM) are reviewed, which include the techniques of SCM, millimeter-wave (mm-wave) generation and reception at base stations, and optical multiplexing/demultiplexing. The impact of system nonlinear distortions and their suppression are also reviewed. I...
With the growing requirement for advanced speeds and better capacity brought about by speedy data expansion on the Internet, Optical time division multiplexing attracted much attention for its high speed operations and ability to overcome the electronic bottleneck problems. In this article, 4x10 Gb/s WDM/OTDM conversion using super continuum(SC) generation at 100Ghz is proposed for 12Km, 24Km a...
One bi-directional passive optical network (PON) based on optical code-division multiple access with interference elimination is proposed. By combining with wavelength division multiplexing (WDM) technique, the proposed scheme alleviates the noise arising during photo-detecting process in the PON. Therefore, the bit error rate performance is improved, which is demonstrated by the results of per...
