      Multi-parameter optical gauge based on mode coupling effect in asymmetric index multi-core fibres 

      Arrizabalaga Uriarte, Oskar ORCID; Sun, Qi; Lee, Timothy; Zubia Zaballa, Joseba Andoni; Velasco Pascual, Javier; Sáez de Ocáriz, Idurre; Schülzgen, Axel; Amezcua Correa, Rodrigo; Brambilla, Gilberto; Beresna, Martynas (Elsevier, 2022-07)
      An optical gauge based on coupled multi-core fiber is proposed and experimentally demonstrated. By using direct laser writing to selectively break the fiber index profile symmetry, asymmetric mode coupling between cores ...
