We demonstrate a single-drive push-pull silicon Mach-Zehnder Modulator (MZM) with a !-phase-shift voltage of 3.1 V and speed up to 30 Gb/s.

The concentricity of an optical fiber in a plastic coating affects the fiber strength, transmission loss, and the connectorization process.

The field of high-speed measurements for optical telecommunication systems is reviewed. An emphasis is placed on diagnostics evaluating the temporal electric field of light, i.e.

We report on the performance of a 38 GHz Quaternary phase shift keyed (QPSK) modulator/demodulator at information rates up to 8 Gbit/s.

GaAs-AlGaAs quantum-well (850 nm) vertical-cavity surface-emitting lasers, with lateral current injection and shallow implanted apertures, show small signal modulation bandwidths of at least 11 GHz

We have implemented a monolithic electronic 50 Gb/s 4:1 MUX core in an InP-based HBT technology.

The invention of permalloy and its application to submarine cables have led to the installation of transoceanic cables of many times the traffic-carrying capacity of the former non-loaded cables.

We develop a gain-switched quantum cascade (QC) laser to generate pulses with less than 200 ps duration at 8 μm gain switching is a simple technique for the generation of picosecond light pulses fr

We report on a simple technique for the generation of short pulses of midinfrared (5 and 8 mu m) radiation, based on gain-switched quantum cascade lasers.

We report the millimeter-wave performance of enhancement mode InP metal-insulator-semiconductor field-effect transistors grown by chloride vapor phase epitaxy.
