Regrowth-free monolithic vertical integration of passive and active waveguides
… the data rate within the existing bandwidth. Mach-Zehnder Modulators achieve high spectral density by modulating both the phase and amplitude of light. At the moment, laser light sources and Mach-Zehnder Modulators are built discretely and packaged and coupled thereafter. Photonic Integrated …

All optical systems for terabit network era
… development of optical combs based on external modulators to provide transmitters with a large number of optical carriers. Then, the implementation of an experimental all-optical super-channel through the use of optical signals and wavelength manipulations is described. Finally, a novel …

Environmentally stable, near-infrared, mode-locked fibre lasers for industrial applications
… A novel method of active stabilisation of the Mach-Zehnder Modulator was demonstrated, which allowed turn-key operation and maintained low jitter mode-locking for > 50 hours. When combined with stabilisation of the cavity length, timing jitters of < 42 fs (10 Hz to 10 MHz) can be achieved for a …

Analog integrated photonics
… Next, we describe the development of two modulators meant for analog applications: an integrated, linearized Mach-Zehnder modulator and an integrated single-sideband modulator, both of which are measured to have impressive performance. Then, we discuss the development of an integrated …

SPECTRALLY EFFICIENT MULTICARRIER SYSTEMS FOR FIBER-OPTIC TRANSMISSION
… FFT-based OFDM system, a simple dual-drive Mach-Zehnder modulator (MZM) was employed in the transmitter and direct detection in the receiver, which provided an OFDM system implementation with reduced complexity. The data was transmitted through 675km uncompensated standard single-mode fiber …
