Two-dimensional Platinum Diselenide Waveguide-Integrated Infrared Photodetectors
Shayan Parhizkar, Maximilian Prechtl, Anna Lena Giesecke +11
Low cost, easily integrable photodetectors (PDs) for silicon (Si) photonics are still a bottleneck for photonic integrated circuits (PICs), especially for wavelengths above 1.8 …
Monolithically Integrated Perovskite Semiconductor Lasers on Silicon Photonic Chips by Scalable Top-Down Fabrication
Piotr J Cegielski, Anna Lena Giesecke, Stefanie Neutzner +11
Metal-halide perovskites are promising lasing materials for realization of monolithically integrated laser sources, the key components of silicon photonic integrated circuits (PICs…
Overlay Accuracy Limitations of Soft Stamp UV Nanoimprint Lithography and Circumvention Strategies for Device Applications
Piotr Jacek Cegielski, Jens Bolten, Jung Wuk Kim +5
In this work multilevel pattering capabilities of Substrate Conformal Imprint Lithography (SCIL) have been explored. A mix & match approach combining the high throughput of nanoimp…
Integrated perovskite lasers on silicon nitride waveguide platform by cost-effective high throughput fabrication
Piotr Jacek Cegielski, Stefanie Neutzner, Caroline Porschatis +8
Metal-halide perovskites are a class of solution processed materials with remarkable optoelectronic properties such as high photoluminescence quantum yields and long carrier lifeti…
Reflective Arrayed Waveguide Grating with Sagnac Loop Reflectors in Silicon-on-Insulator with Gaussian Pass-band
Bernardo Gargallo, Pascual Muñoz, Rocío Baños +4
In this paper the experimental demonstration of a Silicon-on-Insulator Reflective Arrayed Waveguide Grating (R-AWG) is reported. The device employs one Sagnac loop mirror per arm i…
Novel layout for reflective arrayed waveguide gratings based on Sagnac loop reflectors with custom spectral response
Bernardo Gargallo, Pascual Muñoz
A novel layout for a reflective Arrayed Waveguide Grating is presented in this paper. The device consists of one half of a regular AWG where each arm waveguide in the array is term…
Time-resolved characterization of the formation of a collisionless shock
H Ahmed, ME Dieckmann, L Romagnani +11
We report on the temporally and spatially resolved detection of the precursory stages that lead to the formation of an unmagnetized, supercritical collision-less shock in a laser-d…
