| 内容記述 | Terahertz (THz) refers to the region of the electromagnetic spectrum that lies in between the infrared and microwaves. This frequency range possesses great potential to host several applications in wide-ranging fields, such as wireless communications, astronomy, non-invasive imaging and security scanning. However, despite sustained progress over the past decade, THz technology has not yet reached the level of maturity and flexibility of the neighboring radio frequency (RF) and optical range. One missing key aspect is the ability to integrate advanced beam control functionalities within a monolithic platform. A promising approach to achieve this goal is to combine within a single device two features of the neighboring ranges: optical microcavities, that can sustain efficient lasing operation; and antenna arrays, providing a high level of beam control. In this thesis, we investigate via simulations fabrication and characterization the emission properties of arrays of patch antenna-coupled microcavities embedding quantum cascade active regions. The geometrical configuration of the array allows independent and simultaneous tuning of the losses governing the microcavities as well as beam shaping by constructive interference in the far-field. We show that optimized arrays emit THz with unprecedented low beam divergence and robust lasing in single frequency and spatial mode. Additionally, we demonstrate polarization functionalization by coupling the patch antenna microcavities with plasmonic wires. This feature introduces an additional degree of freedom to adjust the relative emission from the cross-polarized modes of the patch, allowing the device to radiate with any coherent polarization state from linear to circular. Finally, we discuss how this design can further enable other advanced functionalities such as active beam steering and control of THz non-linearities. The successful implementation of integrated advanced functionalities and sources on-a-chip demonstrates the ability of our platform to replicate in the THz range the beam control concepts used in the RF and optics, thus paving the way towards establishing a mature technology in this range of the electromagnetic spectrum. | |||||||
