Achieving distinctive modulation across short-wave infrared (SWIR) regions while enabling precise phase control at low signal loss within a compact footprint remains an ongoing challenge. By integrating CuCrP2S6 (CCPS) into silicon photonics microring resonators (MRR) an international team of researchers (United Arab Emirates, New York University) enhanced light-matter interaction and measurement sensitivity to minute phase and absorption variations. The devices exhibited low optical losses and excellent modulation efficiency. These results outperformed earlier findings on phase shifters based on TMDs. The study demonstrated distinct variations in electro-optic tuning sensitivity when comparing transverse electric and transverse magnetic modes, revealing a polarization-dependent response that paves the way for diverse applications in light manipulation. The potential applications CCPS devices range from phased arrays and optical switching to their use in environmental sensing and metrology, optical imaging systems, and neuromorphic systems in light-sensitive artificial synapses… read more.
