Vertical Integration of Dual Wavelength Index Guided GaAs-Lasers

Karouta, F; Jagadish, Chennupati; van Roy, B; Tan, Hark Hoe


The vertical integration of two GaAs-based lasers operating at different wavelengths has been achieved with the use of re-growth technology. A V-channel substrate inner stripe structure was used for the bottom laser and a ridge waveguide for the top laser. Both lasers shared a common electrode and can be powered independently or simultaneously. This represents a promising method for fabricating integrated lasers with different wavelengths.
