The dye-doped TNLC optical transistor.

(a) The schematic diagram of a TNLC transistor. (b,c) Optical controllability (D27 concentration = 0.76 wt %) — relation between emitter transmission, collector power and base power. (d) Fan-out — magnification factor with varying base powers, different colors stand for different dye concentrations.
