Andrea Melloni with the Optical Communications research group have published in Nature Communications Journal the latest important result of their 10-year long research on slow light propagation in photonic chips.
Nature Communications is an online-only, multidisciplinary journal dedicated to publishing high-quality research in all areas of the biological, physical and chemical sciences. Papers published by the journal represent important advances of significance to specialists within each field.
In the paper it is experimentally demonstrated that, by leveraging slow light propagation in a silicon photonic integrated circuit smaller than 1 mm2, it is possible to convert the wavelength of an optical signal with a significantly higher efficiency with respect to traditional approaches based on “fast” waveguides.
Paper reference: Francesco Morichetti, Antonio Canciamilla, Carlo Ferrari, and Andrea Melloni, “Travelling-wave resonant four-wave mixing breaks the limits of cavity-enhanced all-optical wavelength conversion”.
