Tunable optical filter |
| abstract |
The tunable optical filter comprises a Fabry-Perot cavity (12) and ancontrolled-index device (20). The controlled-index device is located in the Fabry-Perotncavity and has a refractive index responsive to a control signal (22). ThenFabry-Perot cavity has at least one resonant optical frequency that depends on thenrefractive index of the controlled-index device. The Fabry-Perot cavity has anmaximum transmissivity for light having a frequency equal to its resonant opticalnfrequency, and attenuates light whose frequency differs from the resonant opticalnfrequency. Thus, the control signal controls the frequency of the light transmittednby the tunable optical filter. |
