摘要： Semiconductor electro-optical modulators which receives an input optical signal and provides a modulated output optical signal based on an input electrical signal are disclosed. The semiconductor electro-optical modulator may comprise at least one electrical transmission line adapted to carry the input electrical signal and a semiconductor electro-optical phase shifter waveguide electrically coupled to the at least one electrical transmission line. An optical path length of the semiconductor electro-optical phase shifter waveguide between a modulation begin plane of the semiconductor electro-optical modulator and a modulation end plane of the semiconductor electro-optical modulator may be greater than an electrical path length of the electrical transmission line between the modulation begin plane of the semiconductor electro-optical modulator and the modulation end plane of the semiconductor electro-optical modulator.

摘要： An arrayed waveguide grating device includes an input coupler configured to receive a light signal and split the light signal into a plurality of output light signals. The device also includes a plurality of waveguides optically connected to the input coupler, each waveguide having a plurality of waveguide portions having respective sensitivities to variance in one or more parameters associated with operating of the optical arrayed grating device. Lengths of the respective portions are determined such that each waveguide applies a respective phase shift to the output light signal that propagates through the waveguide and the plurality of waveguides have at least substantially same change in phase shift with respective changes in the one or more parameters associated with operation of the device. An output coupler is optically connected to the plurality of waveguides to map respective light signals output from the plurality of waveguides to respective focal positions.

摘要： Optical waveguides may include a substrate and a silicon based optical waveguide supported on the substrate. The silicon based optical waveguide may include a central ridge portion and a plurality of spaced apart wing portions connected through connecting portions. The number of wing portions may be greater than two. The central ridge portion may have a central ridge lateral width extent greater than a lateral width extent of at least one of the wing portions. Optical waveguides may include a substrate, a silicon based optical waveguide supported on the substrate, and a concentrator supported on the substrate and positioned within a lateral width extent of the silicon based optical waveguide and outside of a height extent of the silicon based optical waveguide. The optical waveguides may be included as part of an optical modulator.

摘要： Disclosed are various embodiments for a multi-tip laser coupler with improved alignment guidance. A photonic integrated circuit (PIC) includes an input interface, an output interface, and a waveguide array. The waveguide array includes a first waveguide, a second waveguide, and a third waveguide. The first waveguide and the third waveguide are coupled to the input interface and are not coupled to the output interface. The second waveguide is coupled to the input interface and the output interface. Further, the second waveguide is positioned parallel to and between the first waveguide and a third waveguide. The second waveguide includes a tapered body such that an output end of the second waveguide coupled to the output interface is wider than an input end of the second waveguide coupled to the input interface.
