13th Nov 2006, 22:42 GMT
J. S. Xia, Y. Ikegami, Y. Shiraki, N. Usami, and Y. Nakata Freestanding hexagonal two-dimensional photonic crystal (PhC) microcavities with Ge self-assembled quantum dots were fabricated on silicon-on-insulator substrates. Strong photoluminescence associated with Ge quantum dots was observed in the wavelength region of 1.21.6 [mu]m at room temperature. Sha ... [Appl. Phys.
