Abstract

The invention discloses a quick aligning method and a device of an integrated photonic device. The method comprises the following steps: using a multi-mode array optical fiber to carry out initial alignment in the optimal aligning process of a first single mode array optical fiber and an integrated photonic chip; then converting the multi-mode optical fiber into a second single mode array opticalfiber; and carrying out the optimal alignment of the first single mode array optical fiber, the integrated photonic chip and the second single mode array optical fiber by an alignment algorithm. The multi-mode array optical fiber is characterized by using the multi-mode optical fiber with the core diameter of 62.5 microns, and the optical fiber is encapsulated and fixed in a V-shaped groove with aproper specification. The invention has the characteristics of low cost, high efficiency and easy operation and can be generally suitable for the alignment and encapsulation process of the integratedphotonic chip.

Description

Technical field [0001] The invention relates to a method and device for rapid alignment of integrated photonic devices. The method and device are mainly suitable for the alignment and packaging of array optical fibers and integrated photonic chips. Background technique [0002] Integrated photonic devices have outstanding advantages such as compact structure, small size, strong anti-interference ability, good performance consistency, stability and reliability, and ease of automated mass production. In recent years, they have been widely used in optical communication backbone networks and fiber-to-the-home technologies for access networks . In the process of manufacturing integrated photonic devices, the packaging of array fibers and waveguide devices is a very important and critical part, and the packaging cost accounts for 70% to 90% of the total cost, and the packaging time accounts for more than 50% of the total production time. So a stable and fast packaging method will make...
