Abstract
Optical interferometers are the basis for measuring quantities such as distance, velocity, acceleration, temperature, protein binding, and chemical concentration. However, reaching shot noise limited sensitivity is challenging in most cases and usually only possible in tabletop setups in specialized labs. Weak value amplification, an effect discovered by Aharonov and Vaidman in 1988, has been shown to enable shot noise limited sensitivity. In this talk, we will discuss how to amplify the phase signal in a photonic interferometer without increasing technical noise using weak value amplification. We will review weak value amplification and show how it is ideally suited for implementation on a photonic chip. We will show recent advances and how they can enhance the performance of interferometric sensors.
