Optomicrowaves devices

Convertisseur O/E rapide calibré jusqu'à 65 Ghz
Several equipments are available for microwave-photonics devices characterizations like E/O and O/E converters used by researchers. For example, a calibrated optical test set with an integrated laser source at 1300nm and a high-speed photodetector can be used up to 20GHz. A 65GHz gold calibrated O/E converter is also at researchers' disposal for very high speed applications.

Other equipments for digital signals generation and analysis allow data transmission evaluation of performances in microwave-photonics architecture systems.

Génerateur de signaux numériquesTwo kinds of generators are proposed. A pseudo-random bit generator is used for high bit rate PRBS signal up to 3Gbits/s. A vector signal generator can be used when complex modulations are needed.

Traitement et analyse des liaisons numériques
Two kinds of receivers are available for signal treatment and analysis parts of digital links. A complete system consists of a frequency translator receiver and an analogue to digital converter, all included on VXI format and associated with software. It provides full characterization of the link. Furthermore, a high bandwidth digital scope (up to 6GHz) can be used for real time domain analysis of transmitted signals.
