More specifically relevant. ^ Include optical gratings, hearing instruments, and other optical components Methods and devices to produce hysteresis, support, or protection.

BACKGROUND OF THE INVENTION L ~ Fiber Optic Fiber-Duanxian's job change. The grating has a modulated refractive index along the center of the f-fiber waveguide, and can be formed using periodic changes in UV recording, or other manufacturing processes. The short period, or the charm of the Lion Fiber Bragg Grating, records the changes in light and truncated refractive index. Changes in grating pitch and changes in refractive index with temperature change cause unwanted wavelength shifts in the device. ·. For many applications, fiber gratings must operate over a wide temperature range and minimize changes in spectral characteristics. When the grating peak loss decreases with temperature, the main effect of temperature change is the peak wavelength shift. It is temperature-dependent, and the performance is compensated by connecting the fiber grating to a substrate with a negative coefficient of thermal expansion. In one approach, the fiber grating's hysteresis, or temperature compensation, is formed by connecting it to small talents with a nepheline ceramic matrix having a negative coefficient of thermal expansion. At least two component frits connect the optical fiber to the matrix and the epoxy resin deposit to relieve strain. Optical fiber gratings attached to a matrix are usually embedded in a protective fluorogel coating and enclosed in a hermetically sealed metal box to provide protection from humidity. The design is determined by the fact that the frit as a whole is connected to a flat surface with a mismatched coefficient of thermal expansion. Stress is generated at the interface between the flat surface and the glass frit. The packaging manufacturing involves a large number of processes as well as intensive manual processes.
