WebDec 1, 2008 · When the Bragg reflectors are infinite, the waveguide supports guided modes inside the overlapped bandgaps of the two Bragg reflectors. Each mode can be labeled unambiguously with three mode orders, which reflect explicitly the features of the mode-field distribution in the guiding layer and the Bragg Acknowledgement WebFeb 9, 2024 · This is also the case for Bragg-reflection waveguides (BRWs) targeting parametric down-conversion (PDC) to the telecom C-band. The large non-linear coefficient of the AlGaAs alloy and the strong confinement of the light enable extremely bright integrated photon pair sources.
