Kolenov, D. (author), Esmaeil Zadeh, I.Z. (author), Horsten, R.C. (author), Pereira, S.F. (author)Coherent Fourier scatterometry (CFS) has been introduced to fulfil the need for noninvasive and sensitive inspection of subwavelength nanoparticles in the far field. The technique is based on detecting the scattering of coherent light when it is focused on isolated nanoparticles. In the present work, we describe the results of an experimental...journal article 2021

(author)In this paper, the design and the characterization of a novel interrogator based on integrated Fourier transform (FT) spectroscopy is presented. To the best of our knowledge, this is the first integrated FT spectrometer used for the interrogation of photonic sensors. It consists of a planar spatial heterodyne spectrometer, which is...journal article 2019

Ouyang, B. (author), Haverdings, Michael (author), Horsten, R.C. (author), Kruidhof, Marten (author), Kat, Pim (author), Caro-Schuurman, J. (author)We present a compact integrated photonics interrogator for a ring-resonator (RR) ultrasound sensor, the so-called MediGator. The MediGator consists of a special light source and an InP Mach-Zehnder interferometer (MZI) with a 3 × 3 multi-mode interferometer. Miniaturization of the MZI to chip size enables high temperature stability and...journal article 2019

Grillo Peternella, F. (author), Ouyang, B. (author), Horsten, R.C. (author), Haverdings, Michael (author), Kat, Pim (author), Caro-Schuurman, J. (author)We experimentally demonstrate an interrogation procedure of a ring-resonator ultrasound sensor using a fiber Mach-Zehnder interferometer (MZI). The sensor comprises a silicon ring resonator (RR) located on a silicon-oxide membrane, designed to have its lowest vibrational mode in the MHz range, which is the range of intravascular ultrasound (IVUS...journal article 2017

(author)We present a broadband quantum cascade laser-based spectroscopic system covering the region between 850 and 1250 cm?1. Its robust multipass cavity ensures a constant interaction length over the entire spectral region. The device enables the detection and identification of numerous molecules present in a complex gas mixture without any pre...journal article 2014
