    Abstract: Methods are disclosed of fabricating an optical assembly. An active optical element is disposed near or on a first surface of a slab of optical material. A passive optical element is formed on a second surface of the slab, with the second surface being substantially parallel to the first surface. An optical axis of the passive optical element is aligned with an optical path between the passive optical element and an active region of the active optical element using a lithographic alignment process.

    Abstract: Methods and structures are disclosed demultiplexing optical signals transmitted over an optical fiber into a silicon substrate and to multiple detectors. The silicon substrate has two spaced-apart surfaces and a diffractive element disposed adjacent to one of the surfaces. Each of the optical signals corresponds to one of multiple wavelengths. The optical signals are directed into the silicon substrate along a path through the first surface to be incident on the diffractive element. The path is oriented generally normal with the first surface and/or with the diffractive element, which angularly separates the optical signals such that each of the wavelengths traverses through the substrate in a wavelength dependent direction to the first surface. Each optical signal is steered from the first surface towards the second surface to be incident on different optical elements that direct them generally normal to the first surface to be incident on one of the detectors.

    Abstract: A method of fabricating on a substrate an optical detector in an optical waveguide, the method involving: forming at least one layer on a surface of the substrate, said at least one layer comprising SiGe; implanting an impurity into the at least one layer over a first area to form a detector region for the optical detector; etching into the at least one layer in a first region and a second region to form a ridge between the first and second regions, said ridge defining the optical detector and the optical waveguide; filling the first and second regions with a dielectric material having a lower refractive index than SiGe; and after filling the first and second regions with the dielectric material, removing surface material to form a planarized upper surface.
