Abstract

The reflection of a finite duration optical pulse from a semi-infinite nonlocal medium for various ABC's is investigated theoretically. We have obtained explicit expressions for the amplitude and phase of the transient reflected field (local and nonlocal) and evaluated them numerically for different ABC's. The effects of spatial dispersion for the reflected transients associated with the light pulse are important for laser frequency at the vicinity of an excitionpolariton resonance. For various ABC's, we find quantitative differences in the magnitude of the amplitude and phase which can be used to analyse different ABC's experimentally. The time decay of the transients has also been obtained.
