Abstract
Generally, the fabrication of distributed Bragg reflector (DBR) and distributed feedback (DFB) lasers requires regrowth over a grating. While fabricating the devices, special measures must be taken to preserve the grating during the regrowth. Moreover, surface preparation techniques are needed to remove grating fabrication contamination before regrowth. Utilizing surface gratings to fabricate DBR lasers solves the problem of regrowth. This is demonstrated by the formation of first-order DBR gratings on a 0.74 μm-thick upper cladding structure by chemically-assisted ion beam etching and electron-beam lithography.
