MXER-LN series

Very High Extinction Ratio Intensity Modulators

PHOTLINE MODULATOR

The Photline MXER-LN series of intensity modulators is a family of highperformance modulators exhibiting superior Extinction Ratio. Their specificdesign relies on Ixblue “Magic Junction” (patent n° US2008193077).
MXER-LN series intensity modulators are key devices in all applications
where a combination of high extinction and high bandwidth is required: laser
pulse picking prior optical amplification, pulse generation or lidar based
sensing systems are a few examples, as well as fiber optics sensors.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional
operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure
to absolute maximum ratings for extended periods can adversely affect device reliability.
