Tunable Coupler–Augmented Microrings: Reconfigurable Q‐Factor Control for Foundry‐Scale Quantum Light Sources

Nanophotonics, Volume 15, Issue 6, 27 March 2026.
Scalable quantum photonics require robust realization of quantum light sources for foundry‐scale fabrication. An interferometrically coupled silicon nitride microring resonator enables post‐fabrication control of bus–ring coupling. Thermal phase shifters adjust the Q‐factor and the pair generation rate, revealing that optimal generation does not occur ...

Enhanced Spectral Range of Strain‐Induced Tuning of Quantum Dots in Circular Bragg Grating Cavities

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Experimental measurements and finite element simulations together reveal how stiff coating restores strain tunability in circular Bragg grating (CBG) quantum dot devices. Filling the CBG trenches with Al2O3 coating recovers up to 98% of the planar strain (εxx) while preserving cavity performance, enabling bright and tunable quantum light sources ...
