Abstract :
The total performance of an InGaAsP electroabsorption modulator was characterized. Low-driving voltage of 1.2-2.7 V, low fiber-to-fiber insertion loss of 8.4-7.8 dB, and small alpha -value of 0.1-0.4 were obtained in 40-nm-wide wavelength range from 1.53 to 1.57 mu m. Static and dynamic modulation characteristics showed small dependence on the polarization and the power level of input light. Successful applications of a packaged EA modulator to ultralong-distance Er-doped fiber amplifier systems were confirmed by 16000-4550-km transmission experiments at 2.5-10 Gb/s.<>
