Magneto-optical mode conversion was achieved in a waveguide of diluted magnetic semiconductor Cd[sub 1-x]Mn[sub x]Te grown on GaAs substrate. Mode conversion ratio up to 34% under a magnetic field of 5.5 kG was obtained. Cd[sub 1-x]Mn[sub x]Te waveguide showed low optical loss, 4 dB/cm, and high magneto-optical figure-of-merit, 15 deg/dB/kG at λ=790 nm. This result shows the feasibility of monolithical integration of an optical isolator with semiconductor optoelectronic devices. © 2000 American Institute of Physics.

    We report on waveguiding in bundles of parallel oriented semiconductor nanowires, self-assembled from colloidal CdTe nanocrystals in solution at room temperature. Individual bundles, as narrow as 170 nm, act as single-mode, subwavelength waveguides for red visible light. Losses are dominated by...
