Achieving sub-pm wavelength regression via minimum-phase in a single-stream photonic IC

Achieving sub-pm wavelength regression via minimum-phase in a single-stream photonic IC

The authors present a compact photonic chip wavemeter that uses a sparse filter, minimum phase design to measure wavelength with sub-picometer precision, enabling robust and accessible tools for on chip light metrology.

    What is FHMnews?

    FHMnews is the result of a rebellion that transcended frustration. Look around you. As PK puts it, the people in this circle think one thing, say another, and do another. We shook up all three, confined within one circle, and decided to write as they think and speak. News, views, and everything beyond.

    FHMnews is the country's first "new age" English news website. It's modern in its language, attitude, and news standards. It features selected news stories from the day, but with 360-degree coverage. It offers a complete report and analysis of each story, along with additional features like quizzes, polls, memes, and videos.
