Description
Summary:In this work, an organic-inorganic hybrid integrated optical waveguide power compensator based on CsPbBr3 perovskite nanocrystals (PNCs) is first proposed. The inorganic CsPbBr3 NCs waveguide core and the organic copolymer of P(MMA-co-GMA) waveguide cladding are self-synthesized. The optical properties of CsPbBr3 PNCs are analyzed, revealing an appropriate refractive index for improving the gain efficiency of the optical waveguide compensator. The typical hybrid integrated embedded waveguide structure are designed and simulated. The scratching coating technique for fabricating waveguide is adopted. The actual profiles of the waveguide device are characterized. The relative gain coefficient of the actual chip is obtained as 0.93 dB/mm for green 532 nm signal light under 405 nm pumping light. This technique is promising for realizing optical amplification and gain compensation applications of VLC system.
