Abstract :
The absorption properties of hydrogen iodide (HI) near 1.55 mu m are described. Absorption lines of this gas located at wavelengths ranging from 1.534 to 1.594 mu m have been identified. They are proposed as absolute wavelength references for erbium-doped fiber amplifier (EDFA) based multi-channel optical networks.<>
