High-efficiency slow-light modulator on thin-film lithium tantalate operating at high optical power.
Integrated electro-optic (EO) modulators are essential interfaces between electrical and optical signals, but maintaining high modulation efficiency and broadband EO response under high optical power remains challenging. Here, we demonstrate a thin-film lithium tantalate (TFLT) Mach-Zehnder modulator combining 1-mm-lon...
