Temperature-dependent refractive index of AlGaAs for quantum-photonic devices near the bandgap

Moritz Langer, Sai Abhishikth Dhurjati, Martin Bauer +6

We present an experimental method to determine the refractive index of $A{l}_{x}G{a}_{1-x}As$ (x = 0.0 - 0.5) from 300 K to 4 K across the 500 - 1100 nm wavelength range. The values ar…
