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 ...

Linear Technology designed its new LT3905 fixed-frequency, current-mode, step-up dc-dc converter to bias avalanche photodiodes (APDs) in optical receivers. Linear Technology designed its new LT3905 ...

Optical systems have many unique attributes that make them useful for range detection and communications, but often the optical signal needs to be converted to an electrical signal as part of the ...

Researchers in Japan have demonstrated a photodiode optical detector made from organic molecules, in which a current can be generated in two different directions. The direction of the current depends ...

Oclaro’s HL63142DG high power red laser diode is the first ever high power laser diode to offer an inbuilt monitor photodiode at a lasing wavelength of 637nm. It has a unique design which enables ...
