Paper Abstract

We propose and examine single-stack matching-layer enhanced Bragg re ection waveguides as a platform for integrated parametric devices. The proposed designed is asymmetric in geometry, where a multi-layer core is surrounded by a single-layer upper cladding and a lower quarter-wave Bragg mirror. The propagation of the Bragg mode in the new design relies on total internal reection form the upper cladding and Bragg reflectionthe lower periodic cladding. Analytical expressions for modal analysis of TE- and TM-polarized Bragg modes are derived. An AlxGaxAs second-harmonic generation device is theoretically examined to highlight nonlinear performance of the new design and it is compared to symmetric phase-matched Bragg reflection waveguides reported to date.
