Abstract
Description
Technical Field
[0001] This application relates to a manufacturing technology for a co - optical package, especially a co - optical package integrating electronic components, photonic components and optical components and its manufacturing method. Background Art
[0002] Co - Packaged Optics (CPO) is an optoelectronic integration solution based on silicon photonics technology, which can integrate photonic components and electronic components in a single package, thereby achieving high - performance and low - power data transmission and processing.
[0003] Silicon photonics technology uses silicon as the substrate material to manufacture optoelectronic components (such as optical waveguides, optical modulators, detectors, etc.). This technology has the following advantages. (1) High integration: Silicon photonics technology can integrate photonic components and electronic components in a single package to reduce the fiber connections and optoelectronic conversion processes required in traditional optoelectronic components. (2) Low cost: Silicon is the main material in the semiconductor industry, and silicon photonics technology can use existing semiconductor manufacturing processes and equipment to reduce production costs. (3) High speed and low latency: Silicon photonics technology can support high - speed data transmission, and the latency of photon transmission is lower than that of traditional electronic transmission.
[0004] In silicon photonics technology, how to effectively introduce and transmit optical signals is crucial. The following are several common methods. (1) Optical coupling: Use technologies such as micro - lenses and grating couplers to couple external optical signals into photonic components, and the optical coupler can achieve efficient entry and exit of optical signals to ensure the integrity of optical signals. (2) Fiber butt - joint: Directly butt - joint the optical fiber to the photonic component, which requires precise alignment and stable connection technology to ensure low - loss and highly reliable optical signal transmission. (3) Internal light source: Integrate a light source inside the photonic chip to reduce the need for external optical coupling and improve the integration and reliability of the system.
[0005] However, although silicon photonics technology can integrate photonic components and electronic components in a single package, how to effectively introduce optical signals to avoid or reduce optical signal loss is an important part of the successful application of silicon photonics technology, and there is still much room for improvement in this part of the technology.
[0006] In addition, the existing technology cannot effectively integrate electronic components, photonic components and optical components through a single module or circuit structure, nor can it embed photonic components in the circuit structure to combine with specially designed optical components, nor can it form a tapered opening in the circuit structure to quickly align the optical component and the photonic component, and even less can it form an inclined surface on the optical component to simultaneously correspond to the photonic component and the optical fiber.
