Abstract
We report the first demonstration of an InGaAs/InP multiple quantum well Fabry–Perot étalon modulator. The obtained on-off contrast is 5:1 at −16 V applied voltage for 1540 nm wavelength light. The absorption coefficient of the multiple quantum well around 1540 nm increases from 1000 to 6300 cm−1 as the applied voltage increases from 0 to −16 V, and the relative refractive index change is up to −0.9%.Keywords
