Controlling the distribution of information

Abstract: A source generates a request to receive a document. A determination is made regarding an authorization level associated with the source of the request. Another determination is made as to an authorization level required to view the requested document. If the source of the request is authorized to receive the requested document, the requested document is transmitted to the source of the request. If the source of the request is not authorized to receive the requested document, the unauthorized portions of the requested document are redacted and the redacted version of the requested document is transmitted to the source of the request.

Intermodulation distortion and compression in an integrated electrooptic modulator.

Abstract: We have characterized the intermodulation distortion and compression properties of an integrated optical modulator at microwave frequencies by measuring the third-order intercept and 1-dB compression points. Values of +30.0 and +21.4 dBm, respectively, were measured and agree well with theory. When operated in the shot-noise-limited regime, these devices can have spurious free dynamic ranges in excess of 100 dB, making them attractive as potential alternatives to conventional diode mixers in special applications.
