Abstract :
We report a new fabrication technique for multigrating components using a single grating holographic exposure associated with localized selective etching steps. 4-wavelength DBR laser arrays with a 5-nm Bragg wavelength spacing have been demonstrated, showing uniformly very good characteristics.
