Abstract: A device including a chip including a photonic integrated circuit comprising an external cavity for a source of electromagnetic radiation; the source of electromagnetic radiation attached to a top surface of the chip, the source comprising a semiconductor active region comprising, or coupled to, an output for the electromagnetic radiation, wherein the output is oriented to emit the electromagnetic radiation into the top surface in an emission direction that is inclined with respect to a plane of propagation of the electromagnetic radiation in the external cavity; and a coupler coupling the active region to the external cavity via the top surface to integrate the external cavity with the active region. The coupler partially couples the electromagnetic radiation outputted from the active region to the external cavity, and feedback from the external cavity to the active region.

Abstract: A photonic integrated circuit comprising one or more waveguides comprising a second order non-linearity configured to operate on optical pulses each having a pulse length shorter than 1000 optical cycles, as measured at their full width at half maximum. The circuit is configured to generate one or more quantum states carried by one or more of the optical pulses, manipulate one or more of the quantum states, and/or measure one or more of the quantum states.
