IMPIANTO DI COMUNICAZIONE OTTICA A MULTIPLAZIONE A DIVISIONE DI LUNGHEZZA D'ONDA |
摘要 |
Optical device (T1) comprising a waveguide resonator (10), a photodetector (500) and the resonator is adapted to be evanescently coupled to an optical waveguide (F) and optically coupled to the photodetector (500) wherein the resonator is tunable. The device further comprises an intracavity element (50) optically coupled to the resonator, a control circuit element (100 arranged to tune the resonator and further comprising either a receiver (300) or an optical gain element (200). The optical gain device may be located on a loop or interconnecting two loops. |
