Abstract: Disclosed is a polarized light generating device based on an optical waveguide, which includes first to fourth input optical waveguides, respectively, for receiving input light from an outside, first to fifth optical splitters configured to receive at least one light and output the received at least one light as at least one light, and an optical converter configured to receive at least one light from the fifth optical splitter and convert the received light to generate polarized light. The polarized light generating device receives the input light through one of the first to fourth input optical waveguides, and generates a first polarized light, a second polarized light, a third polarized light, and a fourth polarized light. The first to fourth polarized lights belong to elements of two arbitrary two-dimensional mutually unbiased basis sets.

Abstract: In one example, an electronic device comprises a substrate comprising a conductive structure and an inner side and an outer side, a first electronic component over the inner side of the substrate and coupled with the conductive structure, a lid over the substrate and the first electronic component and comprising a first hole in the lid, and a thermal interface material between the first electronic component and the lid. The thermal interface material is in the first hole. Other examples and related methods are also disclosed herein.
