| 摘要 |
A monolithically integrated optical filter which is rapidly tunable over a wide optical frequency range includes an input frequency router connected to an output frequency router by means of selectively activatable transceivers. The transceivers are formed from optically active sections and electronic controllers that selectively modulate, demodulate and amplify a desired one or more of a plurality of multiplexed input optical frequencies. This filter is economical to construct and is useful in high capacity, high speed optical communications networks.
