Optoelectronic devices are crucial for many applications in everyday life: computers, smartphones, connected objects in general.The THz range (0.1-10 THz) still remains industrially unexploited because of the intrinsic difficulties to produce or generate THz photons. However, many applications exist for THz radiation : in the medical field for example, for the sensitive detection of gases, or for the imaging of concealed objects in the visible range.This thesis focuses on quantum well photodetectors (QWIPs) and quantum cascade lasers (QCLs) operating in the THz range in order to develop compact, fast and sensitive devices (but operating at cryogenic temperatures).We used Split Ring Resonators (SRR), inspired by metamaterial research, in ord...
