【摘要】 论述了单模光纤受到弯曲时应力双折射效应的产生。同时探讨了利用这种双折射效应，制作多种在线型光纤器件，包括波片（λ＝１．５５μｍ）、滤波器（中心波长：λ０＝０．６３３μｍ）、声波传感器等。更多还原

【Abstract】 In a bent single mode fiber, lateral compressive stress under the conditions of large deformations induces a birefringence β.This permits us to make some fiber-optic devices such as the analogue of fractional wave plates of classical optics (λ=1.55μm),an in-line spectral-bandpass filter (at a center wavelength of 633 nm)and an acoustic wave sensor etc.更多还原
