Paper Abstract

Photonic time-stretch has been proposed as a signal preprocessor to perform A/D conversion in otherwise inaccessible high frequency regimes. We have demonstrated time-stretching of MM-wave signals at frequencies up to 102 GHz down to 11 GHz , using an electrooptic modulator fabricated with the new polymer material PC-CLD. This application takes advantage of the inherent wideband capabilities of the PC-CLD material system, which has also demonstrated good optical insertion loss and high non- linearity at 1.55 micrometers . The dispersion penalty inherent to time-stretching imposes an additional bandwidth limit to that imposed by the modulator. A single-sideband modulator configuration is proposed to reduced the effect of this penalty.
