| 英文摘要 | A variable wavelength semiconductor laser in which light emitting regions (B₁,B₂), waveguide regions (C₁,C₂) and an active filter region (A₁) including a diffraction grating (5) equipped with a filter function are integrated on a single substrate, whereby only one resonance wavelength is selected to ensure a stable laser operation at a single wavelength of a small oscillation line-width. Further, both light emitting (B₁,B₂) and waveguide regions (C₁,C₂) are disposed on both sides of the active filter region (A₁) substantially symmetrically with respect thereto, thereby allowing ease in adjusting the refractive indices of the respective regions. |
