MICROCAVITES OPTIQUES VERTICALES A BASE DE CRISTAUX PHOTONIQUES MEMBRANAIRES

Abstract : This thesis focuses on the use of slow Bloch modes with radiated losses in 1D and 2D photonic crystal InP, in order to achieve free space reflectors. The primary interest of such reflectors lies in their vertical compactness(one single epitaxial layer), compared with traditional Bragg mirrors, but also in the control on polarization they enable. The rules of design of these reflectors and their fabrication and characterization processes are presented. The experimental results are in good agreement with theory.

These photonic crystal slab mirrors were then incorporated into vertical Fabry-Perot cavities, where they replace the top Bragg mirror. A passive (electrically tunable MOEMS filter, compact and polarized) and an active devices (quantum wells VCSEL, emitting at 1.55μm, compact and polarized) have been made.

Finally, ultimate Fabry-Perot cavities exclusively based on these single-layer Photonic crystal reflectors are studied. The concept is validated using two different samples placed in regards with piezoelectric actuators . Then, a monolithic demonstrator is fabricated and characterized, showing the best known records in selectivity and vertical compactness.
In addition, a theoretical study demonstrates the ability of photonic crystal slab mirrors to highly influence the lateral velocity of light in Fabry-Perot cavities, paving the way for very new interesting applications.
