A traveling-wave-electrode InP n-p-i-n Mach-Zehnder modulator monolithically integrated with a semiconductor optical amplifier was developed. Loss-less operation and full C-band 40-Gbit/s DPSK modulation with a low driving voltage of 3 Vpp was successfully demonstrated.
10-Gbit/s optical duobinary transmission over a 200-km single-mode fiber is demonstrated using a lossless InP n-p-i-n Mach-Zehnder modulator monolithically integrated with a semiconductor optical amplifier. The device gain exceeds 8 dB and the static extinction ratio is over 26 dB for a wavelength of 1550 nm. An error free operation was achieved with a power penalty of less than 5 dB at a low driving...
Full C-band 10-Gbit/s 100-km SMF transmission of NRZ signals is demonstrated using a lossless InP n-p-i-n Mach-Zehnder modulator monolithically integrated with a semiconductor optical amplifier. A power penalty of less than 1.5 dB is confirmed.
An InP n-p-i-n Mach-Zehnder modulator and a semiconductor optical amplifier were monolithically integrated to compensate for the modulator's insertion loss. The device gain exceeded 10 dB, and fiber-to-fiber lossless operation was demonstrated for the full C-band region. The error-free transmission of a 10-Gb/s nonreturn-to-zero signal over a 100-km single-mode fiber was also demonstrated across the...
