| 英文摘要 | There is provided a semiconductor device for aligning a laser (1) with a passive monitor photodetector (2) for quantitative measurements. The semiconductor device comprises: a semiconductor laser (1); a photodetector (2); and a light turning structure (3) bonded on a first substrate. The light turning structure (3) is arranged to deflect light from the back facet of the laser (1) onto the photodetector (2). The light turning structure (3) comprises an etched cavity (4) formed in a separate substrate (6) bonded to the first substrate. Light from the laser may be guided along a groove (7). A reflecting mirror may be provided in the path of the light exiting the laser (1). Where the separate substrate (6) is transparent to the characeristic wavelength of the laser (1), the photodetector (2) may be formed on the underside of the separate substrate (6). |
