Theoretical Analysis of Wavelength Tuning and Power Variation for Complementary Twin-Active-Guide Lasers
Abstract
We present a theoretical analysis, based on the gain levering effect, of wavelength tuning and power variation for complementary twin-active-guide (CTAG) lasers. The wavelength tuning range is strongly dependent not only on a combination of active layer structures but also on drive condition. Furthermore, slope efficiency in output power vs driver current characteristics is controlled by a bias current into one side of the twin-active layer. These simulations agree with the characteristics of fabricated devices measured under pulsed operations.
