Parallel recording with optical waveguide array

We present an analysis of the reading capability of a novel optical pickup consisting of a single-mode and a multi-mode rectangular waveguide. According to the simulations, if one has prior information about the structure of the disk, superresolution readout could be achieved. The proposed system has the advantage to be compact and should be...

Sub-wavelength detection with waveguides in optical recording

We present a study on the use of optical waveguides in readout units for optical recording. Optical waveguides can be used to increase the storage capacity of optical recording, which is limited by diffraction. Optical waveguides are attractive for application in readout units of optical recording systems because it is possible to make compact...
