Abstract
An apparatus, e.g. an optical oscilloscope, includes an optical receiver front end, including an optical device, and an optical delay. The receiver front end is configured to receive at least one input optical signal and produce by the optical device at least first and second output optical signals. The receiver front end is further configured to gate said at least one input optical signal or said at least first and second output optical signals. An optical combiner is configured to combine said at least first and second output optical signals, and the optical delay is located in an optical path of said first optical output signal between said optical receiver front end and the optical combiner. An optical detector is configured to receive a combined optical signal from said optical combiner and to produce therefrom an analog-electrical signal representative of the combined optical signal.
