The invention belongs to the technical field of solid-state electrolytes, and particularly discloses a modified PEO-based composite solid-state electrolyte, a preparation method thereof and a solid-state battery. The modified PEO-based composite solid electrolyte comprises the following components: lithium-doped indium gallium phosphate, PEO and a lithium-based electrolyte, wherein the chemical formula of the lithium-doped indium gallium phosphate is InxGa (1-x) PO4: Li, and x is more than or equal to 0.3 and less than or equal to 0.8. The indium gallium phosphate has an amorphous structure and shows excellent lithium ion transmission performance and conductivity; after lithium ions are further embedded into the indium gallium phosphate with the amorphous structure, the lithium ion conductivity of the indium gallium phosphate can be further improved, and more active sites are provided for transmission of the lithium ions; the lithium-doped indium gallium phosphate is added into the PEO-based solid electrolyte as an inorganic filler, so that the mechanical strength, the ion transmission capability and the conductivity of the PEO-based solid electrolyte can be effectively improved.

The invention discloses a mid-infrared laser based on three-device on-chip integration and a preparation method thereof, relates to the crossing field of a semiconductor laser technology and an optical communication technology, and solves the problem that the existing quantum cascade laser QCL technology cannot give consideration to both high modulation rate and high power. An intermediate infrared laser comprises a QCL unit, an EAM unit and an SOA unit which are sequentially arranged on a substrate. The substrate comprises a semi-insulating InP (Indium Phosphate); the QCL unit, the EAM unit and the SOA unit share the same ridge-shaped waveguide structure and grow through epitaxy butt joint. The method provided by the invention is suitable for a mid-infrared band space communication scene with high requirements on the laser modulation rate, the output power and the single-mode stability.
