英文摘要	Our wafer scale processing techniques produce chip-laser-diodes with a diffraction grating (78) that redirects output light out the top (88) and/or bottom surfaces. Generally, a diffraction grating (78) and integrated lens-grating (78) are used herein to couple light from the chip to an output fiber (74), and the lens-grating (78) is spaced from the diffraction grating (76). Preferably the diffraction grating (76) and integrated lens grating (78) are also used to couple light from the output fiber (74) back to the active region of the chip. The integrated lens-grating (78) can be in a coupling block (82). The use of a coupling block (82) can eliminate "facet-type damage". A coupling block (82) is generally used herein to couple light from the chip to an output fiber (74), and preferably to couple feedback reflected from the fiber (74) back to the chip.
