自主研制了光纤轴向研磨厚度精确控制装置和电弧放电光纤研磨截面高精度抛光装置.通过高精度压电陶瓷PZT调节光纤侧面的研磨厚度,研磨精度达0.01 μm.通过定位传感器控制光纤的研磨长度,可实现长度大于100 mm的光纤侧面研磨.采用低热膨胀系数微晶玻璃作为研磨块.大大降低研磨损耗.微晶玻璃上刻制多个V型槽,可实现多光纤同时轴向研磨,极大地提高了光纤研磨效率.利用电弧放电所产生的高温将研磨光纤的表面进行熔化,从而有效消除研磨光纤表面的粗糙度,抑制微裂纹或凹坑造成的较大损耗.利用上述装置,可精确控制光纤侧面研磨厚度,为高精度双折射可控保偏光纤光栅、基于光纤光栅辅助耦合波分复用(WDM)下话路器等光器件的研究奠定了基础.

An optical fiber side-grinding device with controllable and high-precision grinding thickness,and a setup for high-precision polishing of the optical fiber section by using an arc discharge method were self-made.The precision of side-grinding could reach to 0.01 μm by adjusting the side-grinding thickness controlled by a high-precision piezoelectric ceramics(PZT).The side-grinding length was longer than 100 mm that was controlled by a position sensor.The grinding loss could be decreased greatly by using the oxyfluoride glass with low thermal expansion coefficient as grinding material,and multi-fibers could be grinded at the same time,thus the grinding efficiency was increased greatly.The fiber section was polished with arc discharge,and the loss caused by fiber micro-crack and concave pit would be eliminated effectively.By using the above devices,the side-grinding thickness of optical fiber is controllable and this technique will become the groundworks of the fabrication of birefringence polarization-maintaining fiber Bragg grating (PMF-FBG) with controllable precision and a wavelength-division demultiplexer based on the FBG coupler.
