Summary: This paper proposes a novel type of waveguides called slot hybrid-core waveguides (HCWs) for temperature-independent integrated optical sensors. The HCWs are composed of different core materials with opposite thermo-optic coefficients (TOCs), which makes them immune to temperature variations. Based on this, slot HCWs are proposed for microring resonator-based optical sensors, enabling the sensors to have high sensitivities and temperature independence simultaneously.

Summary: Superconducting quantum circuits are a leading quantum computing platform, and it is crucial to identify and address material imperfections that lead to decoherence for practical advancements. The study used terahertz scanning near-field optical microscopy to probe the local properties of wet-etched aluminum resonators on silicon, revealing higher carrier concentration in silicon within the etched channel compared to buffer oxide etched silicon. The results demonstrate that near-field THz investigations can be used to quantitatively evaluate and identify inhomogeneities in quantum devices.

Summary: Subwavelength grating (SWG) metamaterial waveguides and ring resonators on a silicon nitride platform are proposed and demonstrated. The SWG waveguide achieves a large overlap (53%) of the Bloch mode with the top cladding material, showing great potential for evanescent field sensing and light amplification. Fabricated using a commercial rapid turn-around silicon nitride prototyping foundry process, the devices have critical dimensions greater than 100 nm. Experimental characterization reveals excellent internal quality factor (2.11 x 10(5)) and low propagation loss (approximately 1.5 dB cm(-1)) in the C-band, surpassing silicon-based SWG ring resonators. These results demonstrate the promising prospects of SWG metamaterial structures for silicon nitride based photonic integrated circuits.
