Although advances in photonics and electronics are making it easier and cheaper to implement a light detection and ranging (LIDAR) system, the analog front-end receiver interface still presents many ...

1. This circuit uses a JFET to bootstrap the cathode of the photodiode. It eliminates the effect of diode resistance and capacitance. This improves bandwidth and reduces noise, but puts a dc voltage ...

Direct coupling is advantageous in many photodetector applications, such as viewing laser thresholds and modulation depth. I patented a very fast photodetector mount 1,2 in the early 1970s using these ...

The newly developed waveguide photodiode can be incorporated into various types of programmable photonic devices to measure the intensity of light travelling in the waveguide, with accuracy ...

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 ...

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be major ...

APDs (avalanche photodiodes) or APDs, are common components in laser-based fiber-optic systems for converting optical data into electrical form. The bias voltage and current measurement requirements ...

SI Sensors design novel CMOS image sensors for ultra-fast cameras that increase the velocity of the signal electrons allowing them to be swept out of the photodiode and be detected much faster.
