Abstract:
An optical sub-assembly (OSA) module for suppressing optical back-reflection and effectively guiding light from a light source to an optical waveguide is disclosed. The module comprises a light source for emitting light to said optical waveguide and at least one light transmitting element installed between said light source and said optical waveguide. The at least one light transmitting element is arranged to have a configuration for avoiding light to reflect back to the light source and to cause a light beam from said light source to point to said core of said optical waveguide. Thereby, the working distance is increased, and the assembling process of the OSA module is simplified. This new optical design scheme will greatly improve the optical characteristics of an OSA module, increase the optical transceiver propagation distance, and reduce the difficulty of OSA assembly process.
Abstract:
A display including a supporting layer, a flexible layer and a display structure is provided. The display structure has a top side and a bottom side which are opposite to each other. One of the supporting layer and the flexible layer is disposed at the bottom side of the display structure, and the other one of the supporting layer and the flexible layer is disposed at the top side or the bottom side of the display structure. When the supporting layer and the flexible layer are both disposed at the bottom side of the display structure, the flexible layer is located between the supporting layer and the display structure.
Abstract:
An optoelectronic device includes a base part and a lens cap. The base part has an optoelectronic chip mounted thereon. The lens cap is mounted over the optoelectronic chip and includes a metallic hollow cylindrical part and a plastic inner cylindrical part. The hollow cylindrical part has an opening on a top thereof. The inner cylindrical part is firmly coupled within the hollow cylindrical part, and the inner cylindrical part has a lens part located within the opening and at least three aligning members in contact with an upper circumference of the base part so as to align the lens part with the optoelectronic chip.
