Free-space optical communications

Near or Mid-IR free-space optical (FSO) communications can be the best choice for short and middle range telecommunications or electronic device networking under extreme conditions, usually met in military environments.  They can hardly be intercepted by unwanted observers, and transmission rates can easily be higher than 1Gb/s.

Diode laser emitters are the most suitable laser sources for this application. They are compact, efficient and inherently robust, given its monolithic architecture. Nonetheless military technology always demands to be a step ahead, and this is what we do at Monocrom. Our modules are manufactured solder-free, through our patented ClampingTM technology. Clamped diode laser emitters have important advantages compared to soldered ones. Since clamping is a cold process, laser bars do not show any residual stress due to dissimilar coefficients of thermal expansion (CTE) between the electrodes (usually copper), soldering interface and laser bar itself. Just mechanical pressure guarantees excellent thermal and electrical contact between laser diodes and electrodes, as well as mechanical stability. Moreover, ClampingTM technology allows efficient heat extraction from both p and n side. Our lasers have been proven to withstand strong temperature cycling, mechanical vibrations and shocks, according to military standard MIL-STD-810.
