Figure 38: Left: Numerically-optimized filter-cavity parameters for a single cavity based pre-
and post-filtering schemes: half-bandwidth (solid lines) and detuning (dashed lines),
normalized by [see Eq. (442)], as functions of the filter cavity specific losses . Right: the
corresponding optimal SNRs, normalized by the SNR for the ordinary interferometer [see Eq. (455)].
Dashed lines: the normalized SNRs for the ideal frequency-dependent squeeze and homodyne angle
cases, see Eqs. (403) and (408). ‘Ordinary squeezing’: frequency-independent 10 dB squeezing with
. In all cases, , , and .
