3 pages, 4 figures, 2 tables<br/>We present theoretical estimates for a high-speed, low-loss, all-optical transistor using a micro-resonator device, whose fields interact evanescently with Rubidium vapor. We use a four-level electromagnetically induced absorption scheme to couple the light fields of the transistor. We show results indicating that a weak control beam can switch a much stronger signal beam, with contrast of greater than 25 dB and loss less than 0.5 dB. The switching timescale is on the order of 100 ps.<br/>
