Abstract
A calculation method for tunable twin-guide (TTG) laser tuning characteristics and the threshold current density depending on the modulation layer band-gap wavelength is presented. Experimental results for a 1.5 µm range TTG laser fabricated by all MOVPE are given for the first time. The optimized band-gap wavelength of the modulation layer is approx. 1.3 µm ∼1.4 µm and the maximum tuning range is approx. 9 nm by analysis. In the preliminary fabrication, the threshold current was 23 mA and the tuning range was 2.6 nm.Keywords
