A photonic crystal fiber (PCF) interferometer that exhibits record fringe contrast (~40 dB) is demonstrated along with its sensing applications. The device operates in reflection mode and consists of a centimeter-long segment of properly selected PCF fusion spliced to single mode optical fibers. Two identical collapsed zones in the PCF combined with its modal properties allow high-visibility interference patterns. The interferometer is suitable for refractometric and liquid level sensing. The measuring refractive index range goes from 1.33 to 1.43 and the maximum resolution is ~1.6 × 10(-5).

一种具有创纪录的条纹对比度（约 40 dB）的光子晶体光纤（PCF）干涉仪得到了展示，并介绍了其传感应用。该器件以反射模式工作，由一段经过精心选择的厘米长 PCF 与单模光纤熔接而成。PCF 中的两个相同的塌陷区与模态特性相结合，可实现高可见度的干涉图案。该干涉仪适用于折射率和液位传感。测量折射率范围为 1.33 到 1.43，最大分辨率约为 1.6×10(-5)。
