Fiber Gratings

Product Description: 

A fiber grating is a permanent periodic modulation of the refractive index along the fiber length which is constructed by exposure of the core to an intense optical interference pattern. It reflects particular wavelengths of light and transmits all others. It has been widely used for telecommunication applications such as dispersion compensation, band-rejection filters, fiber lasers, wavelength selective devices as well as many other fields. A fiber grating is an intrinsic sensor which changes the spectrum of an incident signal due to a change in fiber properties such as strain, temperature or polarization. Precision Micro-optics provides a variety of standard fiber gratings as well as customized fiber gratings with wavelength range from 680nm to 1650nm. Athermal package is available for all fiber grating products.
