Abstract

This paper presents an optical head design that minimizes the component number and miniaturizes the head dimension by using a novel reflective prism-type holographic optical element (PT-HOE) for the next-generation high-density blue-light system with small form factor (SFF). The PT-HOE combines four functions, serving as a folding mirror, a beam-splitter, an aberration correction element, and a servo-signal generation device, which are generally required for a conventional optical pickup head (OPH). It greatly simplifies the system complication and assembly procedure of an OPH. Simulations give the satisfactory results and show the feasibility for realizing a high-density SFF OPH with a simple and compact configuration.
