A technique of optical excitation of SCWs has been applied to investigate InP:Fe. Excellent agreement with the predicted dispersion law was revealed. The concept of an effective quality factor of SCWs was introduced to describe a strong inhomogeneous broadening of the resonance. A reasonable agreement of the experimental data with the proposed model has been found. |
