Enhancement of Modulation Bandwidth for VLC Utilizing Green Mini‐LED Light Source

Advanced Physics Research, Volume 5, Issue 3, March 2026.
This paper investigates three sizes of green Mini‐LEDs for visible light communication, focusing on modulation bandwidth and the impact of atomic layer deposition (ALD) sidewall passivation. ALD significantly enhances bandwidth (up to 21.6%), confirming suppression of nonradiative recombination.
