Abstract

Passive integrated optical components have several advantages over conventional optical components including reduced size and weight, alignment as part of fabrication and integration with planar detectors and electronics. Waveguide lenses are recognized as key components for signal processing and source collimation in integrated optical systems. However, few papers have discussed their application to optical error signal processing for optical recording. Here we present a new type of mode-index waveguide lens used in a half aperture and dual-half aperture format for generating focus and tracking error signals in a test configuration.
