      The EXOplanet high resolution SPECtrograph (EXOhSPEC) instrument is an echelle spectrograph dedicated to the detection of exoplanets by using the radial velocity method using 2m class telescopes. This spectrograph is ...

    • Transmission properties of tapered optical fibres: Simulations and experimental measurements 

      Choochalerm, Piyamas; Martin, Bill; Jones, Hugh; Errmann, Ronny; Yerolatsitis, Stephanos; Wright, Thomas; Buisset, Christophe (2021-10-01)
      We measured the transmission of tapered and untapered optical fibres as a function of input beam numerical aperture at 635 nm. The tapered fibres were fabricated with an adiabatic tapering process from graded and step-index ...
