Valence band-anticrossing in GaP $_{1 - x}$ Bi $_{x}$ dilute bismide alloys: giant bowing of the band gap and spin-orbit splitting energy

Zoe L. Bushell, Christopher A. Broderick, Lukas Nattermann +5

Using spectroscopic ellipsometry measurements on GaP $_{1 - x}$ Bi $_{x}$ /GaP epitaxial layers up to $x = 3.7$ % we observe a giant bowing of the direct band gap ( $E_{g}^{Γ}$ ) and valence…

High-Q photonic crystal cavities in all-semiconductor photonic-crystal heterostructures

Zoe Bushell, Marian Florescu, Stephen Sweeney

Photonic crystal cavities enable the realization of high Q-factor and low mode-volume resonators, with typical architectures consisting of a thin suspended periodically-patterned l…
