Here, we show that a characteristic dependence of the width of the temporal interferogram can be exploited to obtain insights into the amount of second-order dispersion inside the interferometer and to retrieve actual and Fourier-limited ultrashort biphoton correlation times of around 100 fs.

Such interferometers have been successfully realized in bulk and fiber-based configurations. However, rapidly developing integrated technologies provide higher efficiencies, smaller footprints, and pave the way to quantum-enhanced on-chip interferometry. In this work, we theoretically realised an integrated architecture of the multimode SU(1,1) interferometer which can be applied to various integrated platforms. The presented interferometer includes a polarization converter between two photon sources and utilizes a continuous-wave (CW) pump. Based on the potassium titanyl phosphate (KTP) platform, we show that this configuration results in almost perfect destructive interference at the output and supersensitivity regions below the classical limit. In addition, we discuss the fundamental difference between single-mode and highly multimode SU(1,1) interferometers in the properties of phase sensitivity and its limits. Finally, we explore how to improve the phase sensitivity by filtering the output radiation and using different seeding states in different modes with various detection strategies.</jats:p>"}],"date_created":"2021-10-12T08:46:46Z","author":[{"first_name":"Alessandro","last_name":"Ferreri","id":"65609","full_name":"Ferreri, Alessandro"},{"full_name":"Santandrea, Matteo","id":"55095","orcid":"0000-0001-5718-358X","last_name":"Santandrea","first_name":"Matteo"},{"last_name":"Stefszky","full_name":"Stefszky, Michael","id":"42777","first_name":"Michael"},{"first_name":"Kai Hong","orcid":"0000-0003-1008-4976","last_name":"Luo","full_name":"Luo, Kai Hong","id":"36389"},{"id":"216","full_name":"Herrmann, Harald","last_name":"Herrmann","first_name":"Harald"},{"first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263"},{"id":"60286","full_name":"Sharapova, Polina R.","last_name":"Sharapova","first_name":"Polina R."}],"date_updated":"2026-01-16T10:22:10Z","doi":"10.22331/q-2021-05-27-461","title":"Spectrally multimode integrated SU(1,1) interferometer","publication_identifier":{"issn":["2521-327X"]},"publication_status":"published","citation":{"apa":"Ferreri, A., Santandrea, M., Stefszky, M., Luo, K.

Whilst interferometric-based methods generally provide the best results for low-loss waveguides, they are almost exclusively used to provide characterization in cases where the waveguide is spatially single-mode. Here, we introduce a Fabry-Pérot-based scheme to estimate the losses of a nonlinear (birefringent or quasi-phase matched) waveguide at a wavelength where it is multi-mode. The method involves measuring the generated second harmonic power as the pump wavelength is scanned over the phase matching region. Furthermore, it is shown that this method allows one to infer the losses of different second harmonic spatial modes by scanning the pump field over the separated phase matching spectra. By fitting the measured phase matching spectra from different titanium indiffused lithium niobate waveguides to the model presented in this paper, it is shown that one can estimate the second harmonic losses of a single spatial-mode, at wavelengths where the waveguides are spatially multi-mode.</jats:p>","lang":"eng"}],"keyword":["Atomic and Molecular Physics","and Optics"],"language":[{"iso":"eng"}],"issue":"4","year":"2020","publisher":"Optica Publishing Group","date_created":"2023-01-23T09:51:53Z","title":"Interferometric method for determining the losses of spatially multi-mode nonlinear waveguides based on second harmonic generation.","type":"journal_article","status":"public","_id":"38051","user_id":"42777","department":[{"_id":"288"},{"_id":"15"}],"article_number":"5507","publication_status":"published","publication_identifier":{"issn":["1094-4087"]},"citation":{"ama":"Santandrea M, Stefszky M, Roeland G, Silberhorn C.
