Spectrally Multiplexed Single-Photon Emitter - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240011829 titled 'Spectrally Multiplexed Single-Photon Emitter
Simplified Explanation
The patent application describes a system for producing an output photon with a predefined frequency. The system includes a pump module that generates multiple pump fields at different frequencies, a photon pair source module that generates frequency-correlated photon pairs, and a detector module that generates a heralding signal after detecting the first photon of a pair. A non-linear photonic element receives the heralded second photon and a complementary selected pump field to produce an output photon with the predefined frequency. A pump field selector selects a pump field based on the heralding signal for provision to the non-linear element.
- The system produces an output photon with a predefined frequency.
- A pump module generates multiple pump fields at different frequencies.

Original Abstract Submitted
a system is provided for producing an output photon having a predefined frequency. a pump module produces a plurality of pump fields at a plurality of pump frequencies. a photon pair source module generates frequency-correlated photon pairs. a detector module generates a heralding signal subsequent to detecting a first photon of a photon pair, the heralding signal indicative of a frequency of the second photon of the pair. a non-linear photonic element is arranged to (1) receive the heralded second photon and a complementary selected pump field, and (2) to produce an output photon having the predefined frequency. a pump field selector is configured to (1) receive a heralding signal and (2) select, based on the received heralding signal, a pump field of the plurality of pump fields for provision to the non-linear element. methods, controllers and computer-readable media are also described herein.
