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 ...

VO2 Nanocomposite Thin Films Integrated on Glass Substrates for Tunable Properties

Advanced Photonics Research, EarlyView.
This work explores tuning the metal‐to‐insulator transition and optical properties through a novel multifaceted approach using both defect engineering and energy band restructuring. VO2‐Au nanocomposite and VO2 thin films are grown on glass with ZnO buffers using pulsed laser deposition.
