and was initially motivated by the desire to create fibres that guided by means of a photonic bandgap effect. The first successful PCF, however, guided because of an effective refractive index ...

forming a 2D perovskite layer on the surface of the wide-bandgap perovskite subcell. “This 2D perovskite layer served as heterogeneous nucleation sites, facilitating the vertical growth of (100 ...

We are also interested in functional integration of photonic devices with microfluidic, MEMS, photopolymer, and 2D materials to broaden the scope of chip-scale sensing and imaging devices.
