  • Publication number: 20250189732
    Abstract: An example transistor outline package includes an accommodation cavity formed by a transistor cap and a transistor base. A main lens is disposed on a top of the transistor cap and runs through the transistor cap, and is configured to transmit a total light ray. The total light ray includes a first light ray and a second light ray. A first chip, a second chip, and an optical splitting component are disposed in the accommodation cavity. The first light ray is transmitted between the first chip and the main lens, and the first chip is an optical transmitter chip. The second light ray is transmitted between the second chip and the main lens. The optical splitting component is disposed between the first chip and the main lens and is configured to adjust a transmission direction of the first light ray.

  • Patent number: 9519151
    Abstract: An optical multiplexer and a transmitter optical subassembly are provided that relate to the field of optics communications. A light-combining part is formed by using at least one light combiner that can combine two beams of light into one beam of light, and at least two levels of light-combining parts are used to constitute an optical multiplexer, so that 2N beams of light are combined into one beam by using N level of light-combining parts, thereby reducing a package size and packaging loss, and reducing the complexity of a manufacturing process.
