A novel design to achieve phase matching between modes of a vertical distributed Bragg reflector waveguide and those of a conventional total internal reflection waveguide is reported for the first time. The device design and structure lend themselves to monolithic integration with active devices using well developed photonic fabrication technologies. Due to the lack of any modulation of the optical properties in the direction of propagation, the device promises very low insertion loss. This property together with the large overlap integral between the interacting fields dramatically enhances the conversion efficiency. The phase matching bandwidth, tunability and dimensions of these structures make them excellent contenders to harness optical nonlinearities in compact, low insertion loss monolithically integrable devices.
首次报道了一种新颖的设计，用于实现垂直分布布拉格反射器波导模式与传统全内反射波导模式之间的相位匹配。该器件的设计和结构便于使用成熟的光子制造技术与有源器件进行单片集成。由于在传播方向上不存在任何光学特性调制，该器件有望实现极低的插入损耗。这一特性与相互作用场之间的大重叠积分一起，显著提高了转换效率。这些结构的相位匹配带宽、可调谐性和尺寸使其成为在紧凑、低插入损耗的单片可集成器件中利用光学非线性的优秀候选者。
