            Abstract : 
We fabricated and characterized the optical response of MgB2 nanowires with critical temperature TC = 33 K. The devices showed optical response at 4 K and sub-nanosecond relaxation time. The detectors responded to the simultaneous absorption of three photons, but not to single photons.
