Abstract
We describe a novel post-fabrication adjustment method of the oscillation wavelength in distributed feedback lasers where no external control is necessary. The method makes use of refractive index change induced by light irradiation. "Wavelength trimming" of 0.8 /spl Aring/ at 1.55 /spl mu/m is demonstrated.
