© 2015 Optical Society of America. We have built an optical-frequency standard based on interrogating iodine vapor that has been trapped within the hollow core of a hermetically sealed kagome-lattice photonic crystal fiber. A frequency-doubled Nd:YAG laser locked to a hyperfine component of the P(142)37-0 127I2 transition using modulation transfer spectroscopy shows a frequency stability of 3 × 10-11 at 100 s. We discuss the impediments in integrating this all-fiber standard into a fully opticalfiber- based system, and suggest approaches that could improve performance of the frequency standard substantially.
