    "abstract": "A quantum master equation model for the interaction between a two-level\nsystem and whispering-gallery modes (WGMs) of a microdisk cavity is presented,\nwith specific attention paid to current experiments involving a semiconductor\nquantum dot (QD) embedded in a fiber-coupled, AlGaAs microdisk cavity. In\nstandard single mode cavity QED, three important rates characterize the system:\nthe QD-cavity coupling rate g, the cavity decay rate kappa, and the QD\ndephasing rate gamma_perpendicular. A more accurate model of the microdisk\ncavity includes two additional features. The first is a second cavity mode that\ncan couple to the QD, which for an ideal microdisk corresponds to a traveling\nwave WGM propagating counter to the first WGM. The second feature is a coupling\nbetween these two traveling wave WGMs, at a rate beta, due to backscattering\ncaused by surface roughness that is present in fabricated devices. We consider\nthe transmitted and reflected signals from the cavity for different parameter\nregimes of {g,beta,kappa,gamma_perpendicular}. A result of this analysis is\nthat even in the presence of negligible roughness induced backscattering, a\nstrongly coupled QD mediates coupling between the traveling wave WGMs,\nresulting in an enhanced effective coherent coupling rate g = sqrt(2)*g0\ncorresponding to that of a standing wave WGM with an electric field maximum at\nthe position of the QD. In addition, analysis of the second-order correlation\nfunction of the reflected signal from the cavity indicates that regions of\nstrong photon antibunching or bunching may be present depending upon the\nstrength of coupling of the QD to each of the cavity modes. Such intensity\ncorrelation information will likely be valuable in interpreting experimental\nmeasurements of a strongly-coupled QD to a bi-modal WGM cavity.",
