Parametric processes in nonlinear structures with reflections: an asymptotic-field approach
Tadeu Tassis, Salvador Poveda-Hospital, Nicolás Quesada +1
The generation of engineered quantum states of light via nonlinear processes is fundamental for quantum technologies based on photons. Although embedding nonlinear materials within…
Parametric processes in nonlinear structures with reflections: a transfer matrix method approach
Salvador Poveda-Hospital, Tadeu Tassis, Yves-Alain Peter +2
The Transfer Matrix Method is a powerful numerical tool for simulating wave propagation in layered media. It has been widely applied in many fields, although its use is typically r…
Etching Properties of PIN-PMN-PT and its Integration in Electro-Optic Phase Modulators
Salvador Poveda-Hospital, Nicolás Quesada, Yves-Alain Peter
We investigate the etching characteristics of PIN-PMN-PT crystals, exploring various wet etching solutions, reactive ion etching gases, and ion beam etching. The etch rate and surf…
Custom nonlinearity profile for integrated quantum light sources
Salvador Poveda-Hospital, Nicolás Quesada, Yves-Alain Peter
Heralded single-photon sources are a fundamental building block for optical quantum technologies. These sources need to be unfiltered and integrated to have good scalability and av…
