Electric optical fiber grating filter with switchable central wavelength |
摘要 |
An electric optical fiber grating has a central wavelength. The central wavelength of an optical fiber grating can be adjusted under strain. The filter includes a bimetal plate, an elastic structure and an solenoid to achieve the goal of switching the central wavelength of an optical fiber grating. Meanwhile, the bimetal plate can also provide proper passive compensation according to the temperature effect around them so that it is not necessary for the optical fiber grating that can switch central wavelengths, to monitor and conduct feedback control at all times. Thus it does not consume power. Therefore, the electric optical fiber grating filter can both achieve the goal of switching central wavelengths and has the advantage of not being sensitive to temperature.
