(DCT) A Reconfigurable RF Photonics Unit Cell For Integrated Circuits
Abstract
In this work, the integration of a Quantum Dot Mode Locked Laser, that acts as a microwave and millimeter wave source, with a wideband antenna is presented. Two aspects of research are discussed. The first aspect deals with a Mode Locked Laser (MLL) based on quantum dot (QD) materials. Due to the unique properties of the QDs, the QDMLL can expand the range of stable mode-locking operation. The details of the MLL structure and its operation mechanism are discussed by experimenting on a two-section QDMLL. The second aspect of this work is the realization of a compact transmitting antenna integrated to a QDMLL. For this purpose, several antenna prototypes were designed by using the two-port microwave approach. The designed antennas were integrated with laser chips using the lithographic method. The challenges of designing this wideband antenna that can operate at multiple QDMLL harmonics are presented in detail. Moreover, an example of achieving beam-steering using a two-element QDMLL-LTSA phased array by manipulating the laser bias condition is also discussed. The proposed RF/Photonic antenna is a good candidate in realizing a compact phased antenna array system without the use of phase shifters
