    摘要： A device (16) in a system (10) modulates an optical signal (13) and tunes the duty cycle of the optical signal (13) for optimizing system performance as a response of the duty cycle. The device (16) includes a tunable duty-cycle Mach-Zehnder interferometer (MZI) acting as a pulse-width shaper (160) for modulating the optical signal (13) and tuning the duty cycle of the optical signal (13). The MZI (160) has a transmittance transfer function of the interferometer (160). At least one electrode structure (163) generates a DC voltage and an AC voltage for biasing and controlling the swing of the Mach-Zehnder interferometer (160) with the respective amplitudes of the DC and AC voltages such that the maximum power transmittance point on the transfer function is less than 100% for tuning the duty cycle of the optical signal (13) such that system performance is optimized.

    摘要： An optical signal transmission line includes a first fiber adapted to guide an optical signal therethrough and having a first κ, a second fiber adapted to guide the optical signal therethrough and having a second κ of less than or equal to about 100 nm at a wavelength of 1550 nm, and a κ compensating fiber adapted to guide the optical signal therethrough and having a third κ of greater than or equal to about 60 nm at a wavelength of 1550 nm. The first fiber, the second fiber and the κ compensating fiber are in optical communication, thereby defining an optical transmission line having a total dispersion and a total dispersion slope. The first κ, the second κ and the third κ cooperate such that the total dispersion is within the range of about 1.0 ps/nm-km≧total dispersion≧about −1.0 ps/nm-km at a wavelength of 1550 nm, and the total dispersion slope is within the range of about 0.02 ps/nm2-km≧total dispersion slope≧about −0.02 ps/nm2-km at a wavelength of 1550 nm.
