Ultra Narrow Linewidth Phase Shift Fibre Bragg Grating

O/E LAND INC is now capable of providing Ultra Narrow Phase Shifted Fiber Bragg Grating filters with linewidths of 0.6 pm. The Phase Shift forms within the middle of the stop band, as a sharp peak, which can be seen in the transmission spectrum response. The Phase Shifted FBG can be used as transmission filter in telecommunications, and in sensing applications.
