摘要： A polarisation insensitive optical frequency mixer comprising an optical fibre coupler block (2) a silica fibre (6) with a region whose cladding (4) has been polished off close to the core (8) on which is rotatably mounted interdigitated electrodes (12) spaced from the coupler block (2) by a polymer film spacer (12). The electrodes (12) induce a spatially periodic electric field within the core (4) which reverses every half period which provides frequency doubling of light passing through the fibre (6) over the whole grating length. The electrodes are dimensioned to provide polarisation insensitised frequency mixing by providing that the electric field components within the optical waveguide are substantially equal in two mutually orthogonal directions transverse the waveguide.

摘要： A system for conversion or amplification using quasi-phase matched four-wave-mixing includes a first radiation source for providing a pump radiation beam, a second radiation source for providing a signal radiation beam, and a bent structure for receiving the pump radiation beam and the signal radiation beam. The radiation propagation portion of the bent structure is made of a uniform Raman-active or uniform Kerr-nonlinear material and the radiation propagation portion comprises a dimension taking into account the spatial variation of the Raman susceptibility or Kerr susceptibility along the radiation propagation portion as experienced by radiation travelling along the bent structure for obtaining quasi-phase-matched four-wave-mixing in the radiation propagation portion. The dimension thereby is substantially inverse proportional with the linear phase mismatch for four-wave-mixing. The system also includes an outcoupling radiation propagation portion for coupling out an idler radiation beam generated in the bent structure.

摘要： A system for conversion or amplification using quasi-phase matched nonlinear optical wave-mixing includes a first radiation source for providing a pump radiation beam, a second radiation source for providing a signal radiation beam, a bent structure for receiving the pump radiation beam and the signal radiation beam, and an outcoupling radiation propagation portion for coupling out an idler radiation beam generated in the bent structure. A radiation propagation portion of the bent structure is made of a uniform three-dimensional material at least partly covered by a two-dimensional or quasi-two-dimensional material layer and has a dimension taking into account the spatial variation of the nonlinear optical susceptibility along the radiation propagation portion as experienced by radiation traveling along the bent structure for obtaining quasi-phase matched nonlinear optical wave-mixing in the radiation propagation portion. The dimension thereby is substantially inverse proportional with the linear phase mismatch for the nonlinear optical process.
