| 31. | Commonly used classes of semiconductor laser transmitters used in fiber optics include DFB ( Distributed Feed Back ).
|
| 32. | SDL, which makes semiconductor lasers and other products, is one of Spectra-Physics Laser's competitors listed in the filing.
|
| 33. | To explain the actual operation of semiconductor lasers, one must refine this analysis by systematically including the Coulomb-interaction effects.
|
| 34. | Semiconductor lasers reach some 100 m, but small, inexpensive semiconductor lasers have coherence lengths on the order of 1 mm.
|
| 35. | The new device replaces the foot-long ( 30-centimeter-long ) wiring with optical fiber and delivers the electricity via semiconductor laser.
|
| 36. | The same technology might also be used to make blue semiconductor lasers, which are similar in structure but more complex.
|
| 37. | Semiconductor lasers reach some 100 m, but small, inexpensive semiconductor lasers have coherence lengths on the order of 1 mm.

|
| 39. | Vertical cavity surface-emitting lasers ( VCSELs ) are semiconductor lasers whose emission direction is perpendicular to the surface of the wafer.
|
| 40. | In contrast, a conventional in-plane semiconductor laser entails light propagation over distances of from 250 �m upward to 2 mm or longer.
