Abstract

We propose and demonstrate a novel technique for increasing the amplitude of coherent population trapping (CPT) resonance in open Lambda systems. The technique requires no complex modifications to the conventional CPT setup and is compatible with standard micro fabrication processes. The improvement in the CPT resonance amplitude as a function of intensity of the excitation light agrees well with the theory based on ideal open and closed Lambda systems.
