Paper Abstract

Waveguide grating couplers have important applications to optical data storage. Focusing grating couplers eliminate the need for focusing optics and can be used in both read and write modes. It is convenient to fabricate the gratings at short visible wavelengths although they are used at laser diode radiation wavelengths in the near infrared to visible range. This paper discusses a design technique for introducing compensating aberrations during fabrication which account for the wavelength change. A sample design is presented and the tolerance limits on the alignment parameters are derived. 2. 0
