    • A planar lightwave circuit that can be optically coupled with an external device with low optical loss, while also providing low-power functional control over an optical signal propagating through the PLC is disclosed. The PLC includes a high-contrast waveguide region in a stress-inducing (SI) phase shifter is formed such that it can control the phase of the optical signal. The high-contrast-waveguide region is optically coupled to a low- contrast-waveguide region via a spotsize converter, thereby enabling optical coupling to off- chip devices with low optical loss. Formation of the SI phase shifter in a high-contrast- waveguide region enables improved responsivity and phase control, reduced voltage, and smaller required chip real estate. As a result, the present invention enables lower-cost and higher-performance PLC systems.
    • 公开了一种平面光波电路,其可以与具有低光损耗的外部设备光学耦合,同时还提供通过PLC传播的光信号的低功率功能控制。 PLC包括应力诱导(SI)移相器中的高对比度波导区域,以便它可以控制光信号的相位。 高对比度波导区域通过斑点转换器光学耦合到低对比度波导区域,从而使光耦合到具有低光损耗的片外器件。 在高对比度波导区域中形成SI移相器可以提高响应度和相位控制,降低电压以及更小的所需芯片空间。 因此,本发明能够实现低成本和更高性能的PLC系统。

    • One embodiment of the invention provides an optical modulator having a Mach- Zehnder interferometer (MZI) and an optical resonator (460) coupled, via a tunable optical coupler (434), to one of the MZI internal arms (430a, 430b). The optical resonator induces in the MZI response frequency-dependent optical losses characterized by a comb of spectral resonances.
