    摘要： The present invention provides an optical chip 100 and a method 600 for coupling light. The optical chip 100 comprises an input edge coupler 101 having at least one input waveguide 102, and configured to receive light on two orthogonal modes of same polarization. It further comprises a demultiplexer 103 configured to divide the two orthogonal modes into a mode carried on a first intermediate waveguide 104 and a mode carried on a second intermediate waveguide 105 independent from the first intermediate waveguide 104. The optical chip 100 also comprises a polarization multiplexer 103 configured to recombine the modes carried on the intermediate waveguides 104, 105 into two polarization-orthogonal modes carried on one output waveguide 107.

    摘要： A coherent optical mixer circuit is provided that can measure a phase error without requiring a step of cutting away a delay circuit. Odd-numbered or even-numbered two of four inputs of an 4-input-and-4-output multimode interference circuit are connected to an input mechanism. The four outputs of the multimode interference circuit are all connected to an output mechanism to the exterior. Other two inputs of the multimode interference circuit are connected to two monitor waveguides. One of the monitor waveguide is longer than the other to configure a light delay circuit. The monitor waveguides constituting the light delay circuit are connected to the respective outputs of a 2-branched light splitter. The 2-branched light splitter has an input connected to a monitor light input mechanism from the exterior via a monitor input waveguide.

    摘要： A slow-light generating optical device (1) is disclosed. The optical device comprises a planar waveguide (2), and the planar waveguide comprises: a longitudinal extending guiding region (4) with a first side (6) and a second side (8), a first nanostructure (7) arranged on the first side (6) of the guiding region (4), and a second nanostructure (9) arranged on the second side (7) of the guiding region (4). The planar waveguide (2) includes a first longitudinal region where the first nanostructure (7) and the second structure (9) are arranged substantially glide-plane symmetric about the guiding region (4) of the planar waveguide, and the first and the second nanostructures (7, 9) are designed so that the planar waveguide has a band structure and is adapted to guide a forward propagating mode and a backward propagating mode possessing energy bands, which individually are non-degenerate and mutually degenerate, and which intersect each other and form a Dirac point at a Brillouin zone edge. The first and second nanostructures are alternatively defined as designed so that the planar waveguide has a band structure and is configured to guide a forward propagating mode and a backward propagating mode possessing energy bands, wherein the energy band of the forward propagating mode is monotonically increasing as a function of a wave vector within a finite range on both sides of the first Brillouin zone edge and the backward propagating mode is monotonically decreasing as a function of a wave vector within a finite range on both sides of the first Brillouin zone edge, or vice versa.

    摘要： An embodiment waveguide polarization rotator includes an optical waveguide and an overlay strip. The optical waveguide has an input end and an output end oppositely disposed thereon. The optical waveguide is operable to receive, at the input end, an input optical signal having a mode having an input polarization. The optical waveguide is further operable to generate, at the output end, an output optical signal having an output polarization orthogonal to the input polarization. The overlay strip is disposed over and non-orthogonally crosses the optical waveguide. The overlay strip has a first end laterally offset from the optical waveguide by a first offset distance and a second end laterally offset from the optical waveguide by a second offset distance.

    摘要： Polarization rotators of conventional techniques require forming a silicon nitride layer, which is not employed in usual fabrication of a silicon waveguide circuit. In order to employ a polarization rotator function in an optical integrated circuit, a process of forming a silicon nitride layer is added just for that purpose. This increases the fabrication time and complicates the fabrication equipment. In a polarization rotator of the present invention, the waveguide width of a center core portion of a polarization converter (104) is made small. Thus, the intensity of an optical wave does not concentrate only at the center core portion and is more influenced by structural asymmetry. With the configuration of the polarization rotator of the present invention, it is possible to efficiently cause polarization conversion with a structure including only a silicon waveguide and no silicon nitride layer or the like formed thereon.

    摘要翻译： 传统技术的偏振旋转器需要形成氮化硅层，该氮化硅层在通常制造硅波导电路中不使用。 为了在光学集成电路中使用偏振旋转器功能，正好为此添加了形成氮化硅层的工艺。 这增加了制造时间并使制造设备复杂化。 在本发明的偏振旋转器中，使偏振转换器（104）的中心芯部分的波导宽度较小。 因此，光波的强度不仅仅集中在中央核心部分，而且更受结构不对称性的影响。 利用本发明的偏振旋转器的配置，可以利用仅包括硅波导并且不在其上形成氮化硅层等的结构来有效地进行偏振转换。
