Femtosecond Laser Irradiation followed by Chemical Etching (FLICE) is a powerful technique for prototyping three-dimensional structures in glass. Here we show that it is possible to apply FLICE also to a commercial alumino-borosilicate glass, where very complex and low-loss photonic circuitry has been demonstrated recently. As a test for the technique, we realize an optofluidic device composed of a microchannel and two intersecting optical waveguides.

Scaling-up optical quantum technologies requires a combination of highly efficient multi-photon sources and integrated waveguide components. Here, we interface these scalable platforms, demonstrating high-rate three-photon interference with a quantum dot based multi-photon source and a reconfigurable photonic chip on glass. We show that this combination of scalable sources and reconfigurable photonic circuits compares favorably in performance with respect to previous implementations and that merging these platforms could allow 10-photon experiments on chip at ∼40 s−1 rate in a foreseeable future.
