    Abstract

    Since a short resonator structure less than 10 μm in length can be realized with a surface emitting laser, dynamic single mode operation is expected. The amount of shift of the oscillation wavelength is studied under the single mode dynamic condition of this surface emitting laser modulated at a high speed. The following findings are made: When the bias is twice the oscillation threshold current and the degree of modulation is 50 percent, the wavelength shift (the amount of chirping) is approximately 4 A, which is on the same order of the conventional laser. The dependence of the wavelength shift on the device structure is small. Further, it is possible to reduce the wavelength shift to a certain extent by reducing resonator length.
