Abstract: The various technologies presented herein relate to various hybrid phononic-photonic waveguide structures that can exhibit nonlinear behavior associated with traveling-wave forward stimulated Brillouin scattering (forward-SBS). The various structures can simultaneously guide photons and phonons in a suspended membrane. By utilizing a suspended membrane, a substrate pathway can be eliminated for loss of phonons that suppresses SBS in conventional silicon-on-insulator (SOI) waveguides. Consequently, forward-SBS nonlinear susceptibilities are achievable at about 3000 times greater than achievable with a conventional waveguide system. Owing to the strong phonon-photon coupling achievable with the various embodiments, potential application for the various embodiments presented herein cover a range of radiofrequency (RF) and photonic signal processing applications. Further, the various embodiments presented herein are applicable to applications operating over a wide bandwidth, e.g. 100 MHz to 50 GHz or more.

Abstract translation: 本文提出的各种技术涉及可以表现出与行波正向受激布里渊散射（前向SBS）相关联的非线性行为的各种混合声子 - 光子波导结构。 各种结构可以同时引导悬浮膜中的光子和声子。 通过利用悬浮膜，可以消除衬底通路，以消除在常规的绝缘体上硅（SOI）波导中抑制SBS的声子损失。 因此，正常SBS非线性磁化率可达到比常规波导系统可实现的大约3000倍。 由于可以用各种实施例实现的强的声子 - 光子耦合，因此本文提出的各种实施例的潜在应用涵盖射频（RF）和光子信号处理应用的范围。 此外，本文呈现的各种实施例可应用于在宽带宽（例如， 100MHz至50GHz或更高。
