| Abstract(in English) | Semiconductor laser's oscillation wavelengths are altered significantly, when semiconductor laser are exposed to magnetic fields. When we set some bulk type semiconductor lasers oscillating at 780nm in weak magnetic fields (～1.4T), at room temperature (300K). When the magnetic field is applied to the laser diodes parallel to the injection current, we observed that the oscillation wavelength shifted to the longer wavelength (low frequency) side in our preliminary works. In this work, we report the longer wavelength side shift, the lower optical output-power side shift, and the higher side terminal voltage shift of some multi-quantum-well (MOW) laser diodes oscillating at 780nm. We are now introducing the mechanism, in which the temperature rise and the longitudinal magneto-resistance effect cause the characteristics shifts observed in our experiments. |
