Abstract

An optical frequency synthesizer was developed at 1.5-μm wavelength region by utilizing a diode laser whose frequency was locked to an absorption line (P-branch, J=23) of acetylene, a frequency tunable laser, and a waveguide-type optical frequency comb generator. This synthesizer has the frequency tunable range of 1.3 THz around 1.54-μm wavelength and absolute frequency stability of /spl sigma/=4.5×10/sup -10/ at 1 s integration time.
