Ultrafast Fiber Optic Photodetector
-
The DXM20AF Ultrafast Detector is a DC - 20 GHz, fiber-coupled photodetector designed for use in time domain applications in the 1250 nm - 1650 nm wavelength range. The detector produces a clean 18 ps impulse response, shown at the right, that provides a high-fidelity electrical output pulse for each optical input pulse.
The core element of the detector is the fiber-coupled, hermetically sealed microwave detector module. For convenience and simplicity of use, the module is mounted inside a rugged aluminum housing that includes a rechargeable battery with 500 mA·h capacity, current monitor circuitry, and a digital display of the DC photocurrent. The performance of each DXM20AF is factory tested, and the individualized test results are provided with the detector.
