InGaAs Photodetectors Data Sheet

InGaAs Photodetectors

EOT’s InGaAs Photodetectors contain PIN photodiodes that utilize the photovoltaic effect to convert optical power into an electrical current.  When terminated into 50 Ω into an oscilloscope, the pulsewidth of a laser can be measured.  When terminated into 50 Ω into a spectrum analyzer, the frequency response of a laser can be measured.  EOT’s InGaAs Photodetectors come with their own internal bias supply consisting of long-life lithium cells.  Plugging a coaxial cable into the photodetector’s BNC output connector and terminating into 50 Ω at the oscilloscope or spectrum analyzer is all that is required for operation.

Applications:

· Monitoring the output of Q-switched lasers

· Monitoring the output of mode-locked lasers

· Monitoring the output of externally modulated CW lasers

· Time domain and frequency response measurements

Features:

· All InGaAs photodetectors can be ordered with optional wall plug-in power supply
