Arbitrarily-shaped ultrashort pulse waveforms could be synthesized with optimized high-resolution zero-dispersion pulse
shaping system. The system and optimized parameters are analyzed and discussed. It is shown that the optimized pulse
shaping system could resolve frequency components of ultrashort pulse and avoid spatial shaping of individual
frequency components. The specified shaped pulses are generated through our optimized system, which can potentially
improve the performance of optical wireless communication system.
A novel configuration of semiconductor all-optical switch based on Fabry-Perot cavity is proposed. The principle and
structure of this kind of all-optical switch are presented. We also analyze the performance of the all-optical switch. The
wavelength selectivity of the all-optical switch changed with the power of the control light is given. We discuss its
viable application in the future optical switching.
Optical Burst Switching (OBS) functioning as an IP traffic aggregator at the edge of the Optical Transport Network is provided to enhance network flexibility and efficiency. This paper gives an overview of OBS node and the benefits it will bring about. It explains how an OBS node is modeled and simulated under different traffic conditions and gives the effect of Fiber Delay Line (FDL) in OBS node. Finally, the simulation results are presented and the performances of OBS node are evaluated.
In this paper, the process of fabricating coarse wavelength division multiplexing (CWDM) passive components using Fused Biconic Taper (FBT) technology is introduced. The performances and specifications of CWDM passive components are measured and reported. And we compare the performances and cost of this kind of CWDM module with the performances and cost of CWDM module based on thin-film-filter technology and dense wavelength division multiplexing (DWDM) module.
In this paper, we presented the results of bend loss measurements for single-mode optical fiber over wide bend radius 1mm ~ 8mm and wavelength 1530nm ~ 1565nm. The oscillations caused by the coupling between the whispering gallery mode propagating in the cladding and the buffer and the core guided fundamental mode was observed versus both bend radius and wavelength. And a good agreement between the experimental results and the theoretical numerical evaluation was obtained.
Using a spectrum-sliced device composed of two cascaded fiber Bragg gratings, a novel multiwavelength fiber light source is manufactured based on broadband amplified spontaneous emission from Er-doped fiber. Two channels incoherent light near 1550nm with FWHM of 0.23nm, 0.45nm, respectively, output power of above 1mW are obtained. Using this fiber amplifier light source, we transmit a 34Mb/s incoherent light signal over 10 Km single-mode standard fiber. The error floor level is less than 10-9.
