High Bandwidth-Efficiency Solar-Blind AlGaN Schottky Photodiodes With Low Dark Current

Tags:
bandwidth issues

Overview Solar-blind UltraViolet (UV) detectors with cut-off wavelength around 280nm can sense very weak UV signals under intense background radiation. These devices have important applications including missile plume detection, chemical/biological agent sensing, flame alarms, covert space-to-space and submarine communications, and ozone-layer monitoring. Wide bandgap AlxGa1xN alloy is an intrinsic solar-blind material for x > 0.35. Since the first demonstration of solar-blind AlGaN photoconductors, research on high Al-content AlxGa1xN solar-blind detectors resulted in high-performance devices. AlGaN-based solar-blind photodetectors with very low leakage and noise levels, high responsivity, high detectivity, and fast pulse response have been reported.

How closely are you monitoring?

Plug an SNMP (simple network management protocol) or RMON (remote monitoring) agent into a node on the network to get an idea of what it's doing, or use network flow analysis to pick up information about what's being sent over the wire.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
