Abstract
Saturated absorption spectroscopy is performed on the acetylene band near inside photonic bandgap fibers of small and large core diameters. The observed linewidths are narrower in the fiber and vary from 20 to depending on pressure and power. Variations in the background light transmission, attributed by others to surface modes, are significantly reduced in the fiber. The optimum signal for use as a frequency reference in a long, diameter fiber is found to occur at about for of pump power. The saturation power is found by modeling the propagation and attenuation of light inside the fiber.
