Abstract
We demonstrate two liquid-core distributed feedback (DFB) lasers operating side-by-side simultaneously at two different wavelengths with sub-mW thresholds from Rhodamine 6G dissolved in ethylene glycol and 4-(Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran in dimethyl sulfoxide on a single polydimethylsiloxane device.
