| Popis: | International audience; This paper describes for the first time, the design and numerical simulations of an optical modulator from a semiconductor optical amplifier (SOA) inserted into a fibre-optic Sagnac loop electrically modulated by a microwave carrier at 20 GHz frequency and higher. Even though the adopted SOA model presents > 1.4 ns gain recovery time, the device is optically modulated up to 30 GHz because a completely gain recovery is not needed. The interferometric device was shown to present better performance than the solely SOA. It is potentially useful to simultaneously carry out optical modulation, sampling and mixing or to be used simultaneously as a modulator (uplink) and amplifier (downlink) in analogue links. |
