Nanophotonics, Volume 15, Issue 7, 13 April 2026.We experimentally achieve an ultraflat, 4.35‐W all‐fiber supercontinuum spanning from 414 to 1860 nm (3‐dB bandwidth). To our knowledge, this represents the broadest octave‐spanning, visible‐to‐NIR, ultraflat SC source ever reported, which also exhibits maximal visible band coverage. ABSTRACT We propose a method for generating ultraflat supercontinuum (

Journal of Sensors, Volume 2025, Issue 1, 2025.Liquid level measurement (LLM) systems are extensively used in industry. Although most liquid measurement systems are based on indirect measurement, flow‐based monitoring is the most used secondary measuring technique for LLM. A comprehensive review of the existing LLM techniques including optical, image‐based, capacitive, and float sensors is ...
