Optical Sources
Across
- 2. desirable spectral width for optical source
- 6. cavity cavity has mirror at both ends
- 9. distortion drawback of LED
- 10. perfect material containing no impurities
- 11. bias on which depletion width increases
- 13. type Fermi level closer to conduction band
- 14. source that compatible with SMF
- 15. does not exhibit catastrophic degradation
Down
- 1. inversion population of upper energy level is greater than population of lower energy level
- 3. impurity give up an electron to the conduction band.
- 4. outer- shell electrons
- 5. higher external power efficiency than the planar
- 7. heterojunetion- structure
- 8. region where radiative recombination takes place
- 12. geometry which provides optical confinement in vertical direction
