Where to Buy p–i–n Photodiodes

Very fast rise time p–i–n photodiodes for measurement of optical waveforms with rise times starting from 10 ps and spectral coverage from 170 to 2600 nm (VUV to IR) have bandwidths from DC up to 30 GHz. Configurations include free-space, fiber receptacle or SM-fiber-pigtailed options and have compact metal housings for noise immunity. The UV-extended versions of the Si photodiodes are the only commercial products that cover the spectral range from 170 to 1100 nm with a rise time < 50 ps. For maximum flexibility, most models are not internally terminated. A 50 Ohm external termination supports the highest speed operation and a high impedance load generates large amplitude signals. Applications include pulse form and duration measurement, laser synchronization, mode beating monitoring and heterodyne measurements. Balanced photodiodes complement the large selection of models.
