Down
- 1. LED has lambentian output pattern
- 2. ratio of average value of the total multiplied output current to primary unmultiplied photocurrant
- 5. noise associated with intensity fluctuations
- 6. dynamic line broadening in laser
- 8. newly created carries are the cause of further impact ionization
- 10. short length of fiber attached already attached to the source
- 12. high resistivity p-type material deposited as an epitoriorial layer on a p+ substrate
