ABSTRACT:
A laser test probe is configured to include an electronic probe and a pair of optical fibers. The electronic probe is a high speed transmission line that is used to provide the required bias signal, as well as an RF test signal, to a laser being tested. The optical fibers are used to capture the optical output signals from the front and rear faces of the laser. These optical signals are then analyzed by a measurement control unit to assess the performance of the device under test. In its most basic embodiment, the test probe can be used to identify lasers that exhibit an insufficient (in the extreme, non-existent) optical output signal.
