Modal Theory of Phase‐Modulated and Frequency‐Shifting Ring Cavities

Advanced Photonics Research, EarlyView.
We present a theoretical and experimental characterization of the optical modes of dispersionless ring cavities with phase modulators or frequency shifters. Their response to arbitrary modulation acts as a filter for phase‐modulated modes that determine the optical output of passive resonators and lasers. This provides a general framework for analyzing

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides

Advanced Photonics Research, EarlyView.
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...

Self‐Aligned Pillar Arrays Embedding Site‐Controlled Single Quantum Dots for Bright Nonclassical Light Emission

Advanced Photonics Research, EarlyView.
Tilted‐view scanning electron microscope images show arrays of self‐aligned etched GaAs triangular pillars hosting single quantum dots. The main image captures the as‐fabricated morphology prior to dielectric coating, highlighting their uniform geometry.
