- Abstract: Highly reflecting mechanically compliant membranes based on photonic-crystal
patterns have recently gained increasing attention within cavity optomechanics
due to their prospects of reaching high coupling rates in
membrane-in-the-middle experiments. Here we present an analysis and comparison
of four different setups in which highly reflecting membranes can be employed
for cavity optomechanics, and discuss optimal choices w.r.t. the figures of
merit cooperativity and efficiency-weighted cooperativity. The analysis
encompasses three different types of membrane-in-the-middle setups
(membrane-at-the-edge, membrane-in-the-actual-middle, and
membrane-at-the-back), as well as the simple Fabry-Perot cavity. Interestingly,
we identify and propose the membrane-at-the-back setup as an optimal choice in
the limit of negligible membrane parasitic loss, which can reach enormous
enhancements of optomechanical cooperativity, and if implemented with a
low-loss membrane would pave the way to nonlinear optomechanics in the quantum
regime.
