For space applications, the accumulated number of hours of operation and the proven reliability of LiNbO3 modulators make them a very attractive choice compared to solutions using alternative technologies.
LiNbO3 modulators have a long standing proven record of use in many applications with many successful and thorough qualifications ( e.g., Telcordia). They operate over a large wavelength range, ranging from 780 nm to 2050 nm delivering a very broad electro-optic modulation bandwidth very attractive optical performance such as low insertion losses, high extinction ratio, high optical power handling capability.
Over the past years, intensive design works and test programs and qualifications following ESCC standards have been conducted at Exail to improve the environmental performance of the modulators and to make them compatible with space applications for LEO to GEO.
Thanks to their unique combination of performance, LiNbO3 modulators are used in very diverse space applications that include navigation, measure / countermeasure, telecommunications, sensing… For each of these applications, Exail offers a dedicated solution based on a specific modulator design.
