24. In a tuneable laser, comprising a gain section having a waveguide, a tuneable section having a waveguide and a phase change section having a waveguide, wherein a material of the waveguide of the tuning section has a refractive index n, which has a fixed background part n0 and a part Δ
- n which is variable under an external influence, wherein the amount of variation Δ
n is a function of the value of the external influence, the improvement comprises decoupling the value of Δ
n from n0 by incorporating quantum dots into the waveguide. - View Dependent Claims (25, 26)
