An Erbium:Ytterbium codoped microcavity-based laser which is lithographically fabricated from sol-gel is demonstrated. Both single-mode and multimode lasing is observed in the C band (1550nm). The quality factor and pump threshold are experimentally determined for a series of erbium and ytterbium doping concentrations, verifying the inter-dependent relationship between the two dopants. The lasing threshold of the optimized device is 4.2 μW.
