Lucia A. M. Saito received the degree in electrical engineering from Faculdade de Engenharia Industrial – FEI (2001) and holds MSc and PhD issued by Universidade Presbiteriana Mackenzie (2006 and 2012). She is currently a Professor at Universidade Presbiteriana Mackenzie, where she is involved in high-speed 2D materials photonic devices and applications.

 

Lucia’s work focuses on generate, develop and demonstrate novel device concepts to improve high-speed photonics technology such as graphene-based active modulators, photodetectors based on 2D materials, saturable absorbers for ultrashort pulses generation and nonlinear fiber optics analysis. This applied research area propose to perform high-speed photonic device modeling, design and characterization for the development of next generation of optical communication systems.

High-speed photonic devices based on 2D materials

 

Recent advances in research have demonstrated the potential development of graphene's and other two-dimensional materials in electronics and photonics areas. These nanomaterials enable innovative electronics with properties such as transparency, flexibility, water resistance and impact resistance, making them attractive to telecommunications industry. In optical communications specifically, the strong interaction of light with graphene allows you to explore the manufacture of control devices of the optical signals at high speed. Theoretical studies predict ultrafast transmission of upper limits to hundreds of GHz, where electronics and photonics could operate in a hybrid setup.

 

The constant search for excellence in applied research with particular interest in the industrial sector development is the main goal and contribution of MackGraphe Engineering group. Another important contribution is the training of highly skilled engineers in micro and nanofabrication, photonic devices engineering, process development based on two-dimensional materials and characterization of electro-optical systems for high-speed lightwave technology. The undergraduate students, master's and doctoral have the opportunity to develop their research projects in a newly built laboratories and high-tech equipment. Moreover, there is possibility of participation in national and international collaborations with leading research centers in the world.

In the first setup, there are images of optical fiber conector end face with nanomaterials deposited on the surface. The sample is placed between two conectors. In the second case, the monolayer graphene is transferred to the surface of side-polished optical fiber, which the graphene-light interaction happen along the propagation.
