Abstract

The electromagnetic field of tapered dielectric probes for optical recording was examined by the 3D finite-difference time-domain method. The probes with a diameter at the bottom surface of approximately 1/n wavelength exhibited high light beam throughput when compared with conventional metal-coated near-field scanning optical microscope probes. The beam sizes inside the recording media, using LaSFN9 glass and GaP probe, were estimated to be 0.75 and 0.43 wavelength, respectively. The computational study of the scattering field from the recorded mark show that these probe can work in the reflection-detection mode.
