Abstract

The throughput of a single fiber-coupled whispering-gallery microresonator, such as a fused-silica microsphere, can exhibit behavior analogous to electromagnetically induced transparency and absorption (EIT, EIA). These effects enable slow and fast light, respectively, in the form of pulse delay or advancement. Two different methods can be used to realize this behavior; in both methods, the key feature is the use of two coresonant orthogonally polarized whisperinggallery modes of very different quality factor (Q). The first method relies on intracavity cross-polarization coupling when only one mode is driven, and the second method uses a simple superposition of orthogonal throughputs (in the absence of intracavity cross-polarization mode coupling) when the two modes are simultaneously driven. We refer to the behavior observed using the first method as coupled-mode induced transparency and absorption (CMIT, CMIA), and the behavior of the second method as coresonant polarization induced transparency and absorption (CPIT, CPIA). In both cases, polarization-sensitive detection of the throughput is used, and the EIT/EIA analog features are observed on the same polarization component as that of the linearly polarized input. Some predictions of a numerical model of these processes are presented here. In addition to a discussion of these predictions, which assume conditions accessible to experiment, some experimental results are briefly described.
