    • closedAccess   Lead-free FASnI3 laser amplifiers integrated in flexible waveguides 

      Suárez, Isaac; Chirvony, Vladimir; Sánchez-Díaz, Jesús; Sánchez, Rafael S.; Mora-Sero, Ivan; Martínez-Pastor, Juan P. Optica Publishing Group (2022)
      A FASnI3 lead-free perovskite is integrated in a flexible waveguide to demonstrate Amplified Spontaneous Emission. An extremely low threshold, 1 µJ/cm2, is observed together with the formation of narrow random lasing lines ...

    • openAccess   Optical Amplification in Hollow-Core Negative-Curvature Fibers Doped with Perovskite CsPbBr3 Nanocrystals 

      Navarro-Arenas, Juan; Suárez, Isaac; Martínez-Pastor, Juan P.; Ferrando, Albert; Gualdrón Reyes, Andrés Fabián; Mora-Sero, Ivan; Gao, Shou-Fei; Wang, Ying-Ying; Wang, Pu; Sun, Zhipei MDPI (2019)
      We report a hollow-core negative-curvature fiber (HC-NCF) optical signal amplifier fabricated by the filling of the air microchannels of the fiber with all-inorganic CsPbBr3 perovskite nanocrystals (PNCs). The optimum ...

    • closedAccess   Polymer/Perovskite Amplifying Waveguides for Active Hybrid Silicon Photonics 

      Suárez, Isaac; Juarez-Perez, Emilio J.; Bisquert, Juan; Mora-Sero, Ivan; Martínez-Pastor, Juan P. Wiley (2015-08)
      The emission properties of hybrid halide perovskites are exploited to implement a stable and very low power operation waveguide optical amplifier integrated in a silicon platform. By optimizing its design with a poly(methyl ...

    • openAccess   Structural characterization of bulk and nanoparticle lead halide perovskite thin films by (S)TEM techniques 

      Fernández Delgado, Natalia; Herrera, M.; Delgado, F. J.; Tavabi, Amir Hossein; Luysberg, M.; Dunin-Borkowski, R. E.; Juarez-Perez, Emilio J.; Clasen Hames, Bruno; Mora-Sero, Ivan; Suárez, Isaac; Martínez-Pastor, Juan P.; Molina, S. I. IOP Publishing (2019)
      Lead halide (APbX3) perovskites, in polycrystalline thin films but also perovskite nanoparticles (NPs) has demonstrated excellent performance to implement a new generation of photovoltaic and photonic devices. The structural ...

    • openAccess   Tunable light emission by exciplex state formation between hybrid halide perovskite and core/shell quantum dots: Implications in advanced LEDs and photovoltaics 

      S. Sánchez, Rafael; Solís de la Fuente, Mauricio; Suárez, Isaac; Muñoz Matutano, G.; Martínez-Pastor, Juan P.; Mora-Sero, Ivan American Association for the Advancement of Science (2016)
      We report the first observation of exciplex state electroluminescence due to carrier injection between the hybrid lead halide perovskite (MAPbI3–xClx) and quantum dots (core/shell PbS/CdS). Single layers of perovskite (PS) ...
