摘要： An optical source uses feedback to maintain a substantially fixed spacing between adjacent wavelengths in a set of wavelengths in a wavelength comb output by the optical source. In particular, a set of light sources in the optical source provide optical signals having the set of wavelengths. Moreover, the optical signals are output at diffraction angles of an optical device in the optical source (such as an echelle grating), and optical detectors in the optical source determine optical metrics associated with the optical signals. Furthermore, control logic in the optical source provides control signals to the set of light sources based on the determined optical metrics.

摘要： In a chip package, semiconductor dies in a vertical stack of semiconductor dies or chips (which is referred to as a ‘plank stack’) are aligned by positive features that are mechanically coupled to negative features recessed below the surfaces of adjacent semiconductor dies. Moreover, the chip package includes an interposer plate at approximately a right angle to the plank stack, which is electrically coupled to the semiconductor dies along an edge of the plank stack. In particular, electrical pads proximate to a surface of the interposer plate (which are along a stacking direction of the plank stack) are electrically coupled to pads that are proximate to edges of the semiconductor dies by an intervening conductive material, such as solder balls or spring connectors. Note that the chip package may facilitate high-bandwidth communication of signals between the semiconductor dies and the interposer plate.

摘要： A hybrid integrated module includes a semiconductor die mechanically coupled face-to-face to an integrated device in which the substrate has been removed. For example, the integrated circuit may include an optical waveguide that conveys an optical signal, which is fabricated on a silicon-on-insulator (SOI) wafer in which the back-side silicon substrate or handler has been completely removed. Moreover, an optical device may be disposed on the bottom surface of an oxide layer (such as a buried-oxide layer) in the integrated device, and the geometry and materials in the integrated device may be selected and/or defined so that the optical signal is evanescently coupled between the optical waveguide and the optical device.

摘要： In a hybrid integrated module, a semiconductor die is mechanically coupled face-to-face to an integrated device in which the substrate has been removed. For example, the integrated circuit may include an optical device fabricated on a silicon-on-insulator (SOI) wafer in which the backside silicon handler has been completely removed, thereby facilitating improved device performance and highly efficient thermal tuning of the operating wavelength of the optical device. Moreover, the semiconductor die may be a VLSI chip that provides power, and serves as a mechanical handler and/or an electrical driver. The thermal tuning efficiency of the substrateless optical device may be enhanced by over 100× relative to an optical device with an intact substrate, and by 5× relative to an optical device in which the substrate has only been removed in proximity to the optical device.

摘要： An integrated circuit that includes an optical waveguide to convey an optical signal via an optical mode in an on-chip optical waveguide is described. In this integrated circuit, a cross-sectional area of the optical waveguide may be tapered in proximity to an electro-optic modulator in the integrated circuit, such as a germanium electro-optic modulator or a quantum-well (QW) electro-optic modulator. In particular, the cross-sectional area may be tapered from a first diameter distal from the electro-optic modulator to a second diameter proximate to the electro-optic modulator. This so-called ‘inverse taper’ may increase the spatial extent or size of the optical mode, thereby allowing the optical signal to be optically coupled to or from the electro-optic modulator with low optical loss.

摘要： In a laser source, a first optical waveguide includes a gain medium, and a second optical waveguide includes a phase tuner which adjusts a phase value of the phase tuner to specify the wavelength of the laser source. Furthermore, the laser source includes a first ring resonator and a second ring resonator, which, respectively, are optically coupled to the first optical waveguide and the second optical waveguide at opposite ends of the laser source. In particular, coupling wavelengths of the first and second ring resonators may match a wavelength of the optical signal, thereby defining an optical resonance cavity in the laser source and selecting a laser mode of the laser source which is associated with the wavelength. Additionally, the laser source includes an optical amplifier that receives and amplifies the optical signal output from the optical resonance cavity.
