Disordered photonic materials, made up of a random assembly of optical nonlinear crystals, enable a broadband tunability in the random quasi-phase-matching (RQPM) regime and do not require high-quality materials

The effect of varying effective index and random deviations of domain boundary on sum frequency generation (SFG) in quasi-phase-matching waveguides are analyzed and analytical expressions of the conversion efficiency are provided for the first time to our knowledge. By simplifying the coupled equations...

As the GUE computations show, this concentration result is sharp up to the quasilogarithmic factor . The main result of this paper is to improve the concentration result to one more in line with the GUE case, namely with exponentially high probability (see the paper for a more precise state...

Supersymmetric transformation for quasi-isospectral design. In light of the results in Fig. 1, we now consider the following question: 'Is it possible to design nearly uncorrelated (or Brownian) potentials with HB0.5 while preserving the original bandgaps?'. To answer this question positively, we...
