One interaction pathway is the directly near-field coupling between the two meta-atoms. The other interaction pathway is via the continuum in a waveguide functioned as a common bus connecting them. We show that by properly introducing gain or loss into the meta-atoms, the hybrid optical system becomes parity-time (\n                    <jats:inline-formula>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" display=\"inline\">\n                        <mml:mrow class=\"MJX-TeXAtom-ORD\">\n                          <mml:mi class=\"MJX-tex-caligraphic\" mathvariant=\"script\">P<\/mml:mi>\n                          <mml:mi class=\"MJX-tex-caligraphic\" mathvariant=\"script\">T<\/mml:mi>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    ) symmetric, in which the effective coupling rate can be customized by manipulating the length of the waveguide.
