Abstract
The group velocity vg of light in two-port ringresonator (TPRR) circuits with loss is theoretically studied. We point out four possible operation regimes, i.e., “slow��? light with positive v_g, “slow��? light with negative v_g, “fast��? light with negative v_g, and “fast��? light with positive v_g, where “slow��? means |v_g| < c and “fast��? means |v_g| > c, with c denoting the velocity of light in vacuum. The temporal behavior of pulses passing through the TPRR for the four operation regimes and the potential of “slow��? light TPRR either with positive or negative v_g for sensing applications are also discussed.
