Design and implementation of an integrated optical coupler by femtosecond laser written-waveguides in LiNbO_3

摘要

This work presents a particular application corresponding to waveguides manufactured by the femtosecond laser micro-machining technique. More specifically we have conducted the study, design, simulation and implementation of an integrated optical circuit device. Here, a set of integrated 1 x 2 evanescent wave couplers were constructed and tested. These devices have unique constructive features because they take femtosecond laser writing advantages. Additionally, the proposed device is a key element to be implemented in many systems, with a high impact among other technological areas, such as optical communication, sensing and control.
