ABSTRACT:
A setup for providing an optical contact adapted for guiding an optical signal comprises an optical waveguide being adapted for guiding the optical signal and comprising a tip on an end of the waveguide, wherein the tip comprises a transparent elastic material covering the end. A detector is provided for detecting a substantial alignment between the waveguide and an optical path within a device under test, and a first moving unit is used to move the waveguide laterally relative to a longitudinal direction of the waveguide and the device under test until the detector substantially detects the alignment. A second moving unit is adapted to reduce the distance between the tip and the device under test until the tip comes in physical contact with the device under test when the detector has detected alignment.
