Abstract: A package structure including a photonic, an electronic die, an encapsulant and a waveguide is provided. The photonic die includes an optical coupler. The electronic die is electrically coupled to the photonic die. The encapsulant laterally encapsulates the photonic die and the electronic die. The waveguide is disposed over the encapsulant and includes an upper surface facing away from the encapsulant. The waveguide includes a first end portion and a second end portion, the first end portion is optically coupled to the optical coupler, and the second end portion has a groove on the upper surface.

Abstract: A package includes a photonic layer on a substrate, the photonic layer including a silicon waveguide coupled to a grating coupler; an interconnect structure over the photonic layer; an electronic die and a first dielectric layer over the interconnect structure, where the electronic die is connected to the interconnect structure; a first substrate bonded to the electronic die and the first dielectric layer; a socket attached to a top surface of the first substrate; and a fiber holder coupled to the first substrate through the socket, where the fiber holder includes a prism that re-orients an optical path of an optical signal.

Abstract: A photodiode with improved response, particular in the blue light portion of the spectrum, is disclosed. An oxide window is formed adjacent a silicide junction. An etch stop layer is applied over the silicide junction, and the oxide window is then etched to form a thin film. A nitride layer is then applied. The resulting photodiode has increased transmission of blue light.

Abstract: An automatic inversely foldable umbrella includes a skeleton structure provided with a main shaft; an upper runner fixed to one end of the main shaft; a lower runner slidably disposed on the main shaft; a middle runner slidably disposed on the main shaft between the upper runner and the lower runner; plural skeleton linkages having a first rib, a second rib, and a foldable rib; plural linking members with one end pivotally disposed on the lower runner and the other end connected with the first rib; a resilient member disposed between the middle runner and the lower runner, and compressible due to the middle runner and the lower runner movement; a first canopy combined to the upper runner and a second canopy combined to the lower runner for covering the skeleton linkages; and a handle. Therefore, the folding and expanding operation of the umbrella are facilitated.

Abstract: A wind-resistant foldable umbrella includes a main shaft; a runner mounted around the main shaft and sliding between an opening position and a folding position; a first canopy and a second canopy with a central portion thereof fixed to the runner and the top end of the main shaft, respectively; a plurality of the umbrella ribs and a plurality of the pulling elements peripherally disposed around the main shaft and between the first canopy and the second canopy. Two ends of the pulling elements are connected to the corresponding umbrella rib and the runner, respectively. When the runner is at the opening position, the umbrella ribs expand toward the bottom end of the main shaft, so the first and the second canopy expand. Moreover, the umbrella ribs are pulled toward the main shaft by the resilient force from each pulling element.

Abstract: An inversely foldable automatic umbrella includes a main shaft; an operating sleeve and a connecting sleeve mounted around the main shaft; a compression spring with two ends thereof contacting the connecting sleeve and the operating sleeve, respectively; a first canopy with a central portion thereof fixed to the operating sleeve; a second canopy with a central portion thereof fixed to the top end; a skeleton disposed between the first canopy and the second canopy; and a pull-moving mechanism having a sliding unit and a connecting unit. The sliding unit is slidingly disposed on the skeleton. Two ends of the connecting unit are pivotally disposed on the sliding unit and the operating sleeve, respectively. When the operating sleeve is at a folding position to fold up the first canopy and the second canopy, the skeleton is allowed to completely adhere to the main shaft.
