摘要
The effective group index of InGaAsP/InP moderately diluted MQW waveguides grown by MOCVD on InP has been measured in the 1.55 mum spectral region. The used technique is based on the Fourier analysis of the spectral transmission function of a resonant cavity formed by the waveguide itself. Accuracy to the third decimal place is demonstrated, and differences between TE and TM indexes are also evidenced.
