Efficient second harmonic generation (SHG) employing quasi-phase-matching (QPM) method based on the spatial modulation of mode intensity has been demonstrated experimentally and theoretically in the optical fiber coupler system for the first time. The theory of coupling compensation is amended to be applicable for practical optical fiber nanowire (OFN) coupler platform even under strong coupling conditions. A unique OFN coupler composed of two suspended parallel 650 nm diameter OFNs is… CONTINUE READING
