The efficient dynamic modeling of a satellite with flexible solar arrays is established by using the component mode synthesis technique. A flexible satellite model can be defined as the assembly of two sub-structures, central body and solar array. Th

We report on the polarization-mode dispersion (PMD)-induced crosstalk in the presence of polarization scrambling. When the polarization scrambling was used, PMD could generate unwanted intensity modulation and degrade receiver sensitivity. The result

We report on the performance comparisons of the chromatic dispersion-monitoring techniques using pilot tones. The results show that the monitoring technique using phase-modulated pilot tones provides superior performances compared with the technique

The authors propose and demonstrate a simple technique to monitor the optical signal-to-noise ratio (OSNR) of wavelength-division-multiplexing (WDM) signals using the orthogonal delayed-homodyne method. This technique estimates the OSNR by analyzing

We report on the effects of nonlinear crosstalk on the optical polarization-mode dispersion (PMD) compensation in wavelength-division-multiplexing (WDM) systems. An analytical model is presented to describe the effect of nonlinear crosstalk on the fi

A novel mode converter based on a hollow optical fiber is proposed to reduce the differential modal delay penalty in optical transmission over multimode fibers (MMFs). The device adiabatically converts a fundamental mode in a single-mode fiber to a r

We report on the effects of stimulated Raman scattering (SRS) on the pilot-tone-based wavelength-division-multiplexing (WDM) monitoring technique. The SRS-induced ghost tones were measured after compensating the effects of erbium-doped fiber amplifie

We demonstrate a 4/spl times/2.5 Gb/s cold-start WDM system using a synchronized etalon filter. This system automatically operated its transmitter lasers at the standardized wavelengths of 1547.82+n/spl times/0.8 nm (193.686-n/spl times/0.100 THz), w
