Strategies for phase locking and optical PLLs

Overview

In sensitive optical applications, obtaining the most precise measurements often involves stabilizing the laser with an external reference. One way to synchronize the phase of a signal is by using a phase-locked loop (PLL).

During this presentation, we introduce the concept of phase locking and demonstrate how to construct an optical PLL with FPGA-based instrumentation, using a fully digital lock-in amplifier, waveform generator, and phasemeter. You’ll see how to increase measurement precision, reduce experimental complexity, and minimize costs with a reconfigurable suite of instruments. You’ll also find out how to leverage Python for PLL control and feedback.

The webinar includes a presentation, demonstration, and live Q&A session. Presented in partnership with PhotonicsViews, a Wiley publication.
