Wavelength tuning in compact microdisks with InGaAs quantum dots in a well structure

Abstract

The tunability in lasing wavelength of the In<inf>0.65</inf>Ga<inf>0.35</inf>As quantum dots-in-a-well microdisk lasers was observed from λ=1190 to 1270 nm by varying the diameter of microdisk cavities from 1.70 µm to 1.83 µm. The magnitude of continuous tuning range is about 80 nm.
