Arms race and space contests are the things of the past for the first and second world countries. They are now focused on the new prize: The Quantum Technology. Till recently, we saw that the United States was the clear-cut front-runner in the next-gen computing program. NASA, along with Google, was working with the most powerful quantum computer built hitherto.
Interconnections in powerful computers and linking "blades" in data centers will increasingly rely on optical communication links. Currently, this still requires an individual laser with individual control circuitry for each channel. Now researchers at Purdue University have developed a new technology that allows a single laser to transmit data over a number of individually controlled channels, at different frequencies, simultaneously.
In the Diode articles we saw that simple diodes are made up from two pieces of semiconductor material, either silicon or germanium to form a simple PN-junction and we also learnt about their properties and characteristics. If we now join together two individual signal diodes back-to-back, this will give us two PN-junctions connected together in series that share a common P or N terminal.
With recent developments in technologies like MIMO, femtocell and LTE, the RF device testing is reaching new dimensions. Read on to find out what’s new in this field
Spencer Kent stands nervously in front of Team D.R.A.D.I.S.' booth at Rice University's annual Engineering Design Showcase. Judging begins in about 10 minutes, and his teammate Galen Schmidt is frantically typing computer code into a laptop beside the team's custom-made radar system.
Silicone compounds are used in thousands of electronic systems to seal, bond, coat, and encapsulate components, enabling them to perform reliably under challenging conditions. Formulators continue to improve silicones to make them easier to use and to offer a wider variety of properties.
Light Emitting Diodes or LED´s, are among the most widely used of all the different types of semiconductor diodes available today. They are the most visible type of diode, that emit a fairly narrow bandwidth of either visible light at different coloured wavelengths, invisible infra-red light for remote controls or laser type light when a forward current is passed through them.
