Study of collimating laser diode beam by a graded-index optical fibre
Abstract:With an every-electron-count method, we calculate the quantum-confinement induced changes in the small-particle plasmon as manifested in the optical absorption spectrum. The small-particle plasmon, which originates from the local-field modified bulk plasmon, changes for so small particles that the electrons inside are quantum mechanically confined. According to the size and shape of the particle, the quantum confinement can be in one-, two- and three-dimension.
