Abstract :
The dependence of waveguiding loss on the magnetization of Fe pillar embedded into (Al,Ga) As optical waveguide was studied. The optical reading of the magnetization direction of Fe pillar was demonstrated for the pillar size of 3 um times 4 um and 3 um times 8 um with signal-to-noise ratio of 4.8 dB and 6 dB, respectively. This results demonstrates feasibility of using the magnetization dependent loss in a semiconductor/metal waveguide as a reading method for future non-volatile all-optical memory.
