A drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, the chilling outflow of energy from the device can be ...

Researchers at the University of Turku, Finland, have developed an organic infrared photodiode that achieves record-level ...

This application note discusses the design considerations, schematic and component selection to achieve a gamma-photon radiation detector. The design is composed of a PIN photodiode, four low-noise op ...

Optoelectronics hold a range of possibilities for the hardware experimenter — indeed who among us hasn’t added LEDs aplenty to our work? What many of us may be unaware of though is that an LED is also ...

Programmable photonics devices, which use light to perform complex computations, are emerging as a key area in integrated photonics research. Unlike conventional electronics that transmit signals with ...

There is typically a compromise between speed and efficiency when designing silicon photodiodes. Now, researchers have exploited microstructuring to achieve fast and thin devices that are also ...

In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

Schematic of the proposed all-optical RBG: (a) optical chaos, (b) optical sampler, and (c) optical quantizer. DFB, distributed feedback semiconductor laser; PC, polarization controller; VA, variable ...

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to ...
