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 broad spectrum. 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.
