Multifunctional Integration SELEX Sistemi Integrati

The technology developed by Alenia Marconi Systems has allowed us to develop a wide range of custom devices in which numerous functions are integrated into the same optical circuit. Furthermore, we are prepared to collaborate with the buyer in the design and optimisation of the devices with the aim of satisfying custom requirements by using our technological expertise.

LiNbO3 Foundry Services

A foundry service is offered to Customers to exploit the SELEX Sistemi Integrati technological know-how in LiNbO3 processing for integrated optical circuits. 
Customer uses the service to get processed wafer, polished and diced circuits as well as pigtailed and packaged devices. 
Custom integrated optical circuits are realised on the basis of the Customer's designs or starting from the requirements, exploiting the SELEX Sistemi Integrati' design capabilities.
