    摘要: Embodiments herein describe techniques for testing or aligning optical components (205, 225) in a photonic chip (200) using a grating coupler (220). In one embodiment, the photonic chip (200) may include an edge coupler (205) and a grating coupler (220) for optically coupling the photonic chip to external fiber optic cables (920). The edge coupler (205) may be disposed on a side or edge of the photonic chip while the grating coupler (220) is located on a top or side of the photonic chip. During fabrication, the edge coupler (205) may be inaccessible. Instead of using the edge coupler (205) to test the photonic chip, a testing apparatus (805) can use the grating coupler (220) along with a splitter (215) to transfer optical test signals between an optical component in the photonic chip (e.g., a modulator or detector) and a test probe (505) optically coupled to the grating coupler (220).

    摘要: Photonic integrated circuits including controllable cantilevers are described. Such photonic integrated circuits may be used in connection with other optical devices, in which light is transferred between the photonic integrated circuit and one of these optical device. The photonic integrated circuit (302) may comprise an optical waveguide (316) having an end disposed proximate to a facet of the cantilever (312). The orientation of the cantilever (312) may be actively controlled in one or two dimensions, thus adjusting the orientation of the optical waveguide (316). Actuation (318) of the cantilever may be performed, for example, thermally and/or electrostatically. Orientation of the cantilever may be performed in such a way to align the optical waveguide with an optical device (326)

    摘要: Methods of optimizing optical alignment in an optical package are provided. In one embodiment, the optical package includes a laser diode, a wavelength conversion device, coupling optics positioned along an optical path extending from the laser diode to the wavelength conversion device, and one or more adaptive actuators. The method involves adjusting the optical alignment of the wavelength conversion device in a non-adaptive degree of freedom by referring to a thermally-dependent output intensity profile of the laser diode and a thermally-dependent coupling efficiency profile of the optical package. The adjustment in the non-adaptive degree of freedom is quantified such that, over a given operating temperature range of the optical package, portions of the coupling efficiency profile characterized by relatively low coupling efficiency offset portions of the output intensity profile characterized by relatively high laser output intensity and portions of the coupling efficiency profile characterized by relatively high coupling efficiency offset portions of the output intensity profile characterized by relatively low laser output intensity. Additional embodiments are disclosed and claimed.
