Digital-to-analog optical recorder |
摘要 |
A digital-to-analog optical recorder incorporating both CCD and integrated optics technologies which is fabricated as a single integral unit including an electro-optical layer portion and a semiconductor layer portion. Sampling circuits and digital-to-analog converters are implemented on the semiconductor layer portion using CCD technology, and a plurality of optical channel waveguides and electro-optical modulators are implemented on the electro-optical layer portion. Each digital signal is converted into two complementary light spots at the output of the recorder.
