Abstract
We have used reflective electro-optic sampling (REOS) technique combined wi th 20 fs laser pulses to detect coherent phonon signals. We observe the pla smon-phonon coupling mode and its excitation power dependence in InAs. In a ddition, we interpreted relative intensity of coupled mode L- to LO phonon in terms of the numerical calculation based on phenomenological equations o f motion for polarization and lattice displacement.
