We would like to share some thing with you.Just like you all, we too had a lots of enthusiasm to do paper presentations in engineering days.Even though we had great support from our staff, but lack of proper material our interests were squashed.Any how we could succeed but not with complete satisfaction.So we would like to help you and guide you to our possible extent........... :

The advent of large-scale, free-space, opto-electronic interconnections, as demonstrated in recent system prototypes, requires new sampling methods to reveal diagnostic information. Several factors contribute to the difficulty of probing optical communications channels without disrupting their operation. High-speed electronic connections to the chip periphery are not available in sufficient number and would contribute an undesirable thermal load. Electronic and optical physical contact probes would obscure many of the optical channels that are relayed to a common surface of the chip in current systems. Optical sampling provides the better method although many standard techniques are either too time consuming or complex to implement………….. : Click here
Fully processed VLSI GaAs MESFET circuits, available through the MOSIS service, have recently been shown to be electrically stable after 3-h thermal cycles at 500°C. It is therefore feasible to epitaxially regrow photonic device heterostructures directly on high-density electronic circuits yielding monolithic optoelectronic VLSI circuits. The MBE growth, planarhation, and LED fabrication of the first optoelectronic circuit using this novel integration technique are described……….. : Click here
