Light-emitting intra-cavity interferometric (ICI) optical sensors based on channel waveguide structures which include an internal light emitting material and a functionalized region. In some embodiments, the waveguides are made of a sol-gel which incorporates the light emitting material. In some embodiments, the waveguide structure includes an ICI resonator backbone and the ICI sensor is a laser sensor. In some embodiments, the resonator backbone has an interferometric Y-branch shape. In some embodiments, the resonator backbone has a Mach Zehnder interferometer shape. In some embodiments, an ICI laser sensor has an interferometric arrayed waveguide grating shape. In some embodiments, an ICI sensor may be remotely optically pumped and remotely read.
