Abstract

Official abstract text for this publication.

A system testing the speed of a microwave photonic system, having a Mach Zehnder interferometer that includes a first arm with a photonic system to be tested and an amplifier arranged to amplify the output of the photonic system, and a second arm with an attenuator configured to match the output power of the amplifier, with at least one filter arranged at the output of the Mach Zehnder interferometer, the filter having a pass band that includes the center frequency of a continuous wave microwave signal applied to the Mach Zehnder interferometer arms. A continuous wave microwave signal is applied to the input of the Mach Zehnder interferometer, a signal is applied to only the second arm with the photonic link, and the output of the bandpass filter is measured with an oscilloscope and a microwave power detector.

First claim

Opening claim text (preview).

What is claimed as new and desired to be protected by Letters Patent of the United States is: 1. A method for testing the speed of a microwave photonic system, comprising: providing a Mach Zehnder interferometer having a first arm with a photonic link, a delay line, and an amplifier arranged to amplify the output of the photonic link and delay line, and having a second arm with an attenuator configured to match the power at an output of the amplifier in the first arm; providing a bandpass filter arranged at the output of the Mach Zehnder interferometer, the band pass filter having a pass band that includes the center frequency of a continuous wave microwave signal applied to the Mach Zehnder interferometer; applying the microwave signal to the input of the Mach Zehnder interferometer; applying a signal to the first arm with the photonic link and delay line; and measuring an output of the bandpass filter with an oscilloscope and a microwave power detector.
