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
