| titleOfInvention | Method for manufacturing multi-dimensional target waveguide grating and volume grating with micro-structure quasi-phase-matching |
| abstract | A method for manufacturing a multi-dimensional target waveguide grating and volume grating with micro-structure quasi-phase-matching. An ordinary waveguide grating is used as a seed grating, and on this basis, a two-dimensional or three-dimensional sampling structure modulated with a refractive index, that is, a sampling grating, is formed. The sampling grating comprises multiple shadow gratings, and one of the shadow gratings is selected as a target equivalent grating. A sampled grating comprises Fourier components in many orders, that is, shadow gratings, a corresponding grating wave vector is [Formula 1], and the grating profile of all the shadow gratings changes with the sampling structure [Formula 2]. In a case where a seed grating wave vector [Formula 3] and a required two-dimensional or three-dimensional grating wave vector do not match, a certain Fourier periodic structure component of the Fourier components of the sampling structure is used to compensate for the wave vector mismatch. The manufacturing method may be applied to design and manufacture a multi-dimensional target waveguide grating and volume grating for any grating profile, and may simplify the grating manufacturing process and also make possible a variety of grating-based photon devices. |
