3D illustration of the team’s device, in which an external microwave signal induces gain modulation along the entire semiconductor laser to generate widely tunable modelocked pulses/frequency combs.
Researchers tap a terahertz quantum cascade laser to modulate the optical gain within a laser cavity via an external microwave signal—and tune it well beyond the known limit for...

FIGURE 1. Comparison of laser frequency deviation: The unlocked laser (gray) exhibits significant environmental drift, while the analog lock (blue) suppresses most of this noise but is limited by hardware-induced drift and component tolerances. The digital implementation (green) leverages high-speed DSP to achieve a near-zero error signal and provide the superior stability required.
Software-defined FPGA-based approaches enable more flexible, precise, and cost-effective stabilization workflows—particularly for applications such as spectroscopy, interferometry...
