Here, an enhanced frequency noise discriminator is proposed using a cavity-coupled Mach-Zehnder interferometer and demonstrated on a general-purpose programmable integrated photonics platform. The frequency noise measurement sensitivity is similar to the well-known Pound-Drever-Hall architecture but owns a passive, simpler, and more compact design. The proposed structure can be utilized in integrated laser frequency stabilization architectures.
