Latest Patents

Yihua Qi holds a patent for a "High-temperature-resistant metal-packaged fiber Bragg grating sensor and manufacturing method therefor." This patent describes a manufacturing method that utilizes a regenerated fiber Bragg grating obtained through high-temperature annealing as a sensitive element. This approach ensures that the grating remains intact even when exposed to high temperatures. The method employs a magnetron sputtering technique, which allows for better integration of optical fiber and metal, creating an adhesive and conductive layer on the fiber's surface. This process minimizes damage to the optical fiber by avoiding the harsh conditions associated with traditional electroless plating methods. Following the sputtering, an electroplating method is used to thicken and deposit a protective layer, ultimately embedding the optical fiber in a flexible metallic substrate to achieve an all-metal package.
