The longitudinal optical modes of a Fabry-Perot resonator are investigated. We consider (1) the three- and one-dimensional spectral mode density in free space and in standing-wave resonators, (2) the infinite sum of mode profiles, resulting in the Airy distribution, (3) comparison between a two-mirror resonator and an infinite periodic lensguide, and (4) comparison between a two-mirror resonator and a ring resonator. It is consistently deduced that the two counter-propagating waves with wave vectors ±|k| at the same resonance frequency ν and polarization constitute independent optical modes with mode indices ±|q|.
研究了法布里-珀罗谐振腔的纵模。我们考虑了（1）在自由空间和驻波谐振腔中的三维和一维光谱模式密度，（2）无限模式分布的求和，导致艾里分布，（3）两个反射镜谐振腔与无限周期透镜导波的比较，以及（4）两个反射镜谐振腔与环形谐振腔的比较。可以一致地推断出，在相同共振频率ν和偏振下，具有波矢±|k|的两个反向传播波构成具有模式指数±|q|的独立光学模式。
