Claim 8:
9. The narrow linewidth laser according to claim 8, wherein the M-Z compound external cavity structure is a low-loss waveguide structure, the low-loss waveguide structure comprises a waveguide made of a same system of materials transparent with respect to a gain material, or a waveguide composed of a material system different from the gain region, or a waveguide made of a mixture of the same system of materials and a different material system, said waveguide being an InP, GaAs-based In(Ga)As(P) waveguide, an InGa(Al)As(P) waveguide, an SOI-based Si waveguide, an SiN waveguide, a lithium niobate waveguide, an SiNO waveguide, an SiO2 waveguide, or an In(Ga)As(P)/Si or Si/SiO2/InGaAsP hybrid waveguide.
