Gas-filled hollow optical fiber references based on the P(13) transition of the ν1+ν3 band of 12C2H2 promise portability with moderate accuracy and stability. Previous realizations are corrected (<1σ) by using proper modeling of a shift due to line-shape. To improve portability, a sealed photonic microcell is characterized on the 12C2H2 ν1+ν3 P(23) transition with somewhat reduced accuracy and stability. Effects of the photonic crystal fiber, including surface modes, are explored. Both polarization-maintaining (PM) and non-PM 7-cell photonic bandgap fiber are shown to be unsuitable for kilohertz-level frequency references.
基于12C2H2的ν1+ν3带的P(13)跃迁的充气空心光纤参考源有望实现具有适度精度和稳定性的便携性。以前的实现方式通过对线形引起的频移进行适当建模来进行校正（<1σ）。为了提高便携性，对一个密封的光子微腔在12C2H2的ν1+ν3 P(23)跃迁上进行了表征，其精度和稳定性有所降低。研究了光子晶体光纤的影响，包括表面模式。结果表明，保偏（PM）和非保偏7芯光子带隙光纤都不适用于千赫兹级别的频率参考源。
