This work has been motivated by the need to test interoperability of systems carrying voice calls over the IP network.

Integrated terahertz (THz) pulse generation and amplification in a THz quantum cascade laser (QCL) is demonstrated.

Dispersion management is becoming paramount in high-speed wavelength-division-multiplexed lightwave systems, that operate at per-channel rates of 40 Gb/s and higher.

We demonstrate two novel hybrid lasers with the same III-V gain medium.

In today's environment, a typical large business customer's traffic is 80% voice and 20% data.

As the bitrate per channel increases in optical systems, the allowable tolerance for dispersive effects, such as chromatic and polarization mode dispersion, decreases substantially.

We report a ridge waveguide integrated with p-i-n photodetector using Metal Organic Vapor Phase Epitaxial (MOVPE) regrowth technique.

An InGaAs p-i-n photodetector for detection in the 1.0micron- 1.6micron wavelength range has been integrated at the end of a ridge waveguide in InP using a metal organic vapor phase epitaxial (MOVP

We propose and analyze a novel waveguide polarization transformer for reset-free endless polarization control.

There is little doubt that the miniaturization and integration of optical components based on guided opticalwaves will play a significant role in shaping the evolution of lightwave systems for comm
