Record-breaking photodetector captures light in just 125 picoseconds

Electrical engineers at Duke University have created the fastest pyroelectric photodetector ever demonstrated, a device that detects light by sensing the tiny amount of heat it produces when absorbed. The ultrathin sensor can capture light across the entire electromagnetic spectrum. It operates at room temperature, requires no external power source, and can be integrated directly into on-chip…

Light-Emitting Diode and Photodetector for Silicon CMOS Chips

Researchers from MIT have designed a light-emitter and detector that can be integrated into silicon CMOS chips.

The huge increase in computing performance in recent decades has been achieved by squeezing ever more transistors into a tighter space on microchips.

However, this downsizing has also meant packing the wiring within microprocessors ever more tightly together, leading to effects such as signal leakage between components, which can slow down communication between different parts of the chip. This delay, known as the “interconnect bottleneck,” is becoming an increasing problem in high-speed computing systems.

One way to tackle the interconnect bottleneck is to use light rather than wires to communicate between different parts of a microchip. This is no easy task, however, as silicon, the material used to build chips, does not emit light easily, according to Pablo Jarillo-Herrero, an associate professor of physics at MIT.

High performance graphene photodetectors set speed record

Graphene is an ideal material for optical communications systems. A new, waveguide-integrated photodetector from AMO, Germany sets a record high bandwidth for ultrafast, high data rate graphene devices.

Graphene-based technologies are proving integral to the new generation of communications -- enabling high performance optical communication systems through ultra-fast and compact optoelectronic devices. Researchers from the Graphene Flagship working at TU Vienna, Austria and AMO, Germany, have demonstrated ultrafast photodetectors that have the highest reported bandwidth for graphene-based devices, enabling data rates of up to 100 Gbit/s. The research, recently published in Nano Letters, points the way towards graphene applications in high-speed communications systems.

Simone Schuler, a researcher at TU Vienna, explained the importance of increasing data capabilities. "These kinds of photodetectors are typically used in optical data links, which form the back-bone of the internet. The maximum operation speed of a photodetector defines the maximum data rate the detector can receive. So, the faster the photodetector the more data it can receive."
