<p>In optical apparatus (10) for reading, writing or erasing optical disks (40), the optical head is implemented in integrated form. Silicon optical bench technology, including integrated optical waveguides (12, 13, 14), Y-splitters and directional couplers, is used in the design of the tracking, lens focussing, and read/write/erase functions. <IMAGE></p> |
