We propose tunable grating structures implemented by the change of the effective refractive index based on thermo-optic effect in silicon. For resistive heating, p-i-n or pn junction was formed in the grating region and surrounding region was thermally isolated. Fabricated tunable gratings were characterized by fiber-to-fiber measurement and Fourier-imaging system with a variation of the bias ;Stimulated Raman scattering (SRS) is one of the main limits for fiber lasers further power scaling. We report on the suppression of the stimulated Raman scattering in fiber laser amplifier using chirped and tilted fiber Bragg gratings (CTFBGs) for the first time. In this paper, we design and fabricate a CTFBG used to suppress the SRS in 1090 nm fiber laser output, and establish a system to ;Steel Grating,Steel Bar Grating,Metal Grating,Stainless Grating,Steel Pannel,Grating Pannel,I-bar Grating , Find Complete Details about Steel Grating,Steel Bar Grating,Metal Grating,Stainless Grating,Steel Pannel,Grating Pannel,I-bar Grating,Steel Grating from Steel Structures Supplier or Manufacturer-Kumgok Steel Industry.
