Paper Abstract
We experimentally demonstrated improvement in optical disc readout signal quality by homodyne detection. We
introduced an optical phase servo system as an alternative to the phase-diversity detection scheme for stabilization of the
interference signal in homodyne detection, which resulted in further enhancement of readout signal quality.
Experimental results indicate that at least a 16-layer recordable disc can be reliably read out with a jitter of less than 8%
at a 1-mW read power by homodyne detection. The estimated amplification of signal amplitude was 13 times.
