Description:
Go!Foton’s integrated Unidirectional Tap Detector is now available in a 4ch, 8ch, or 10ch array package.
Go!Foton’s Unidirectional Tap Detector combines 3 important optical functions in to a single package: an optical
tap based on Go!Foton’s filter on lens technology, an isolator function achieved through Go!Foton’s proprietary
packaging technique, and a PIN photodiode based on Go!Foton’s proprietary InGaAs fabrication process. The
hermetically sealed InGaAs photo detector has a low dark current, a flat and rapid power response and extremely
high temperature stability across a wide wavelength range. Go!Foton’s filter on lens allows customers to choose
tap proportion as well as wavelength range so that monitoring can be achieved on a single wavelength or a broadspectrum. Now these industry leading performance components are available in Array type packages to support
densely packaged multi-channel power monitoring applications. Fewer component parts result in greater space
efficiency, ease of handling, and inherently higher reliability.
