| 摘要 |
A three terminal optical device (26, 25, 30) is disclosed based on a Sagnac interferometer. Control pulses (29) are coupled into the Sagnac loop (L) which switch the system from transmission to reflection. The control pulses preferably have a different wavelength from the signal, allowing their separation by suitable means for separating different wavelengths. Applications are described for signal routing, unchirped pulse generation, autocorrelation and signal sampling. |
