| Q. |
DH surface emitter generally give |
| A. | more coupled optical power |
| B. | less coupled optical power |
| C. | low current densities |
| D. | low radiance emission into-fiber |
| Answer» A. more coupled optical power | |
| Explanation: the optical power coupled into a fiber depends on distance, alignment between emission area and fiber, sled emission pattern and medium between emitting area and fiber. all these parameters if considered, reduces refractive index mismatch and increases external power efficiency thus providing more coupled optical power. | |
