We described a novel optical label swapping (OLS) modulation was also demonstrated, where this technique can be used for a bundled wavelength-domain-multiplexing (WDM) channels without using an array of pumping light sources.
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 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)
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 propose and demonstrate a reconfigurable multilevel transmitter using a monolithically-integrated quad Mach-Zehnder in-phase/quadrature (QMZ-IQ) modulator with binary driving electronics. Different from previous parallel-integrated quadrature amplitude modulation (QAM) transmitter solutions, only one electrode is required to adjust the relative phase… (More)
Successful transmission of live (real time) video traffic is demonstrated using a prototype 100 Gb/s single-polarization differential quadrature phase shift keying (DQPSK) transmitter and receiver over an in-service 504 km link of the LambdaXtreme ® optical transport platform. Teaming with Verizon Business, we demonstrate the feasibility of upgrading an… (More)
