We investigated an integrated optical modulator consisting of two Mach-Zehnder interferometers. The modulator can generate optical signals in various types of modulation formats, which have advantages for long-haul transmission, optical labeling, etc. By using a fabricated versatile optical modulator having traveling-wave electrodes designed for high-speed… (More)
We experimentally demonstrate a 16-QAM transmitter using a monolithically-integrated quad Mach-Zehnder in-phase/quadrature (QMZ-IQ) modulator with binary driving electronics.
-We described a novel optical label swapping (OLS) technique for optical packet systems using frequency-shift-keying (FSK) optical labeling. High-speed optical FSK signal can be generated by using an external FSK modulator consisting of four optical phase modulators. The FSK modulator was based on optical singlesideband (SSB) modulation technique, and… (More)
We demonstrated the transmission of a 10-GBaud, 16-level optical quadrature amplitude modulation signal over a 75-km single mode fiber. The signal was generated by a quad-parallel Mach-Zehnder optical modulator monolithically integrated on a LiNbO<sub>3</sub> substrate.
We propose and demonstrate an optical minimum-shift-keying (MSK) transmitter using a single-quad Mach-Zehnder (MZ) in-phase and quadrature modulator, where four sub-Mach-Zehnder modulators are monolithically integrated on a main MZ superstructure. Using the proposed transmitter, a MSK signal at bit rate of B could be successfully generated by orthogonally… (More)

By using electro-optic sampling technique, the electric field distribution on a resonant electrode for optical modulation was measured with a resolution in the micrometer range, while the range of measurement area was a few millimeters. The electric field on the asymmetric resonant, electrode is enhanced by series and parallel resonance at thc electrode.… (More)
