Achieving precise phase control in optical applications with digital phase-locked loops
Overview
During this presentation, in partnership with Optica, we introduce the concept of phase locking and show you 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 flexible, software-defined instruments. You’ll also find out how to leverage Python for PLL control and feedback.
What we covered
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). Watch the webinar recording to learn:
- The fundamental components of a phase-locked loop.
- How a single FPGA-based system can help fast-track optical phase locking.
- How to use Python to implement digital PLLs.
The webinar includes a presentation, demonstration, and live Q&A session. Check out the answers to all the live audience questions here.
