By using molecular beam epitaxy and post-growth annealing techniques, we have successfully made GaAs interdigitated photoconductive detectors on D-shaped silica fibers. The detectors exhibit low leakage current and internal photoconductive gains of up to 15 are measured. To our knowledge this is the first realization of active III-V optoelectronic devices on fibers and opens up the possibility of realizing optoelectronic integration and circuits directly on fibers.
