Layered hybrid perovskites (LPKs) have emerged as a viable solution to address perovskite stability concerns and enable their implementation in wide-scale energy harvesting. Yet, although more stable, the performance of devices incorporating LPKs still lags behind that state-of-the-art, multi-cation materials. This is typically assigned poor charge transport, currently caused by choice cations ...

Ultra-narrow wurtzite ZnS quantum wires assembled towards an onion slice shape are synthesized in water using a simple hydrothermal procedure. Wires are formed through an oriented attachment mechanism from wurtzite ZnS spherical particles. Strong confinement effect originated from the narrow width was observed and holds promise for use in broad optoelectronic device application.

We introduce a semi-analytical model of capacitor-based electro-optical modulators. By applying this model, the performance dependence on the primary device parameters can be analyzed and a set of design rules has been developed. c © 2006 Optical Society of America OCIS codes: (250.7360) Waveguide modulators; (250.3140) Integrated optoelectronic circuits

We experimentally demonstrate an 8 × 40 Gb/s all-optical coherent-OFDM system using an on-chip 1 × 8 Fourier-transform based on a modified arrayed-waveguide grating router, showing simultaneous receiving of 8 subcarriers with similar signal qualities.

Thin films of J-aggregate cyanine dyes deposited by layer-bylayer (LBL) assembly exhibit exciton-polariton dynamics when incorporated in an optical microcavity. Such LBL, J-aggregate thin films can be precisely deposited in a specific location in an optical microcavity, enabling the development of previously unachievable optoelectronic devices, as for example, the recently demonstrated resonant...
