Single junction type (a) and the proposed double junction type (b) solar cells are compared with the conventional TANDEM type (c) and the proposed face-to-face type (d) multi-junction connections. A ...

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 ...

Photodiode is a type of light detector capable of converting light energy into either current or voltage, depending upon the mode of operation. Photodiodes are similar to typical semiconductor diodes ...

WASHINGTON, D.C. Oct. 4, 2013 -- Researchers in Japan have developed a new photodiode that can detect in just milliseconds a certain type of high-energy ultraviolet light, called UVC, which is ...

In Case Study: Medical Laser System; Part 1: Stabilizing a Laser Feedback Control Loop, the nonlinear flashlamp in the laser control loop had a parabolic transfer function which was gain-compensated ...
