6. Design, Fabrication, and Evaluation of High-Speed Vertical-Cavity Surface-Emitting Lasers
Abstract : The vertical-cavity surface-emitting laser (VCSEL) is a low cost light source with inherent high speed capabilities. These properties, along with low power consumption and a circular output beam, have made the VCSEL a well established component in digital communication networks, particularly in short reach optical data transmission where links consisting of GaAs-based 850nm VCSELs and multimode fiber have become the standard solution.

7. Multi-level modulation formats for high-speed optical transmission systems
Abstract : Over the past several years, the use of multi-level modulation formats has enabledsignificant improvements in the field of optical fiber communication, particularlyin terms of per-channel bit-rate (i.e., line-rate) and spectral efficiency (SE), byencoding multiple bits per symbol.

8. Nonlinear intrachannel distortion in high-speed optical transmission systems
Abstract : The Kerr nonlinearity in optical fibres tends to generate signal distortion in dispersion-managed fibre-optic communication systems. Within a wavelength channel, the resulting intrachannel effects are timing jitter, i.e. READ MORE

9. III-V Nanowires for High-Speed Electronics
Abstract : III-V compound materials have long been used in RF applications in high-electron-mobility-transistors (HEMTs) and bipolar-junction-transistors (BJTs). Now, III-V is also being viewed as a material candidate for replacing silicon in the n-channel in CMOS processes for increased drive currents and reduced power consumption in future nodes. READ MORE
