Observation of wavelength bistability in the interferometric Y-laser

摘要

Abstract: We report on wavelength-bistability in the symmetrical interferometric Y-laser. Two single mode spectra separated by 5.5 nm are observed at identical bias and changed through ramping of only one of the four currents by 17 mA. It is thus controlled as simple as wavelength tuning of our new asymmetrical Y-laser. !10
