    • PURPOSE: A wavelength tunable ring laser is provided to adjust a wavelength selection range and an oscillation bandwidth stably by configuring independent optical element through a simple structure. CONSTITUTION: In a wavelength tunable ring laser, an optical amplifier(11) outputs an optical signal according to an operation current. The optical amplifier amplifies an optical signal by being synchronized with the optical signal wavelength inputted to a feedback input part. A variable band pass filter(14) filters the optical signal of the specific wave length from an output light signal of the optical amplifier. The optocoupler(15) feedbacks a part of the optical signal filtered through the variable band pass filter to the optical amplifier. The optocoupler outputs a remainder which is left after filtering the optical signal through the variable band pass filter to the output terminal. The first and the second polarization controllers(12,13) arrange a polarization state of the optical signal so that they have a maximum transfer rate and a gain.
