The JDSU ETX 500T and ETX 1000T series large-area InGaAs PIN
photodetectors have photosensitive areas with diameters of 500 and 1000 µm,
respectively. These photodiodes offer high responsivity in the 800 – 1700 nm
spectrum, and are designed for use in instrumentation, sensing, and range-
finding applications.
The detectors feature high sensitivity and linear spectral responsivity over a broad
range of input powers. When operating in photovoltaic mode, a noise current
density of 10 fA/Hz^1/2 is typical at room temperature. When reverse-biased for
greater bandwidth, a noise floor of 60fA/Hz^1/2 at -5 V is typical. Linear spectral
response results from the low series resistance of the photodiodes.
The ETX 500T and ETX 1000T series are optimal for the high-speed, differential
mode measurements common in precision optical power meters, optical fiber
identifiers, and optical loss test sets.
The ETX 500T and ETX1000T photodiodes are packaged in hermetically-sealed
TO cans.
