title: Odd waveguide mode quasi-phase matching with angled and staggered gratings.
abstract: Angled and staggered gratings are used for quasi-phase matching of antisymmetric TM(10) modes in periodically poled lithium niobate waveguides with high efficiency. Control of the symmetry of the nonlinear coefficient d adds a new degree of freedom in the choice of which waveguide modes will interact in a quasi-phase-matched device.
