Abstract
An optical measurement system in which a coherent light source generates a light signal, and a launch stage receives the light signal from the light source and generates a test signal. The test signal is launched along an optical path. The launch stage includes a first IQ modulator for controlling the test signal. The optical measurement system further includes a local oscillator stage configured to generate a local oscillator signal, wherein local oscillator stage has a second IQ modulator for controlling the local oscillator signal. A detector stage of the system is configured to receive the local oscillator signal from the local oscillator stage and a scattered signal from the optical path, and interfere the local oscillator signal with the scattered signal. The optical measurement system is implemented with one or more photonic integrated circuits.
