| 摘要 |
A method for switching from a first optical path optically coupled to an optical processing device to a second optical path, said first and second optical path optically connecting, in parallel configuration, a first optical switch to a second optical switch, according to the following steps: directing an optical radiation comprising at least a first operating wavelength through the first optical path to the optical processing device, which is tuned to the first operating wavelength; tuning a resonant all-pass filter optically coupled to the second optical path so as to match, at least at a wavelength adjacent to the first operating wavelength, a phase distortion introduced by the optical processing device on said optical radiation; synchronously actuating the first and the second optical switch so as to switch said optical radiation from the first optical path to the second optical path. |
