Abstract

Recent progress of communications requires the next generation of fiber optic communication systems such as wavelength multiplexing system (WDM) or optical time division multiplexing system (OTDM). For the demand on increase of transmission capacity, it is important to consider the wavelength dispersion of an optical fiber network and the gain spectrum of an erbium doped fiber amplifier. In order to realize above fiber optic systems, several wavelength standards are now under development.^1),2),3) In this paper, we describe the construction and the specifications of a light source stabilized to an absorption line of hydrogen cyanide (HCN) gas on 1.55µm band.
