By leveraging inverse design techniques, we optimize the coupler’s geometry to maximize power transfer while maintaining fabrication feasibility by improving mode overlap and directional emission, addressing the challenge of low coupling efficiency caused by size mismatch and material incompatibility. Simulations demonstrate a substantial enhancement in photon extraction and waveguide coupling. This approach can be extended to other photonic devices, offering a versatile framework for improving quantum light-matter interactions in integrated photonics."}],"author":[{"id":"53444","first_name":"Henna","orcid":"0000-0001-7730-3489","full_name":"Farheen, Henna","last_name":"Farheen"},{"first_name":"Yuheng","last_name":"Chen","full_name":"Chen, Yuheng"},{"last_name":"Chen","full_name":"Chen, Peigang","first_name":"Peigang"},{"full_name":"Kryvobok, Artem","last_name":"Kryvobok","first_name":"Artem"},{"full_name":"Peana, Samuel","last_name":"Peana","first_name":"Samuel"},{"first_name":"Alexander","last_name":"Senichev","full_name":"Senichev, Alexander"},{"first_name":"Vladimir M.","full_name":"Shalaev, Vladimir M.","last_name":"Shalaev"},{"first_name":"Alexandra","last_name":"Boltasseva","full_name":"Boltasseva, Alexandra"},{"id":"158","first_name":"Jens","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens","last_name":"Förstner"},{"last_name":"Kildishev","full_name":"Kildishev, Alexander V.","first_name":"Alexander V."}],"status":"public","department":[{"_id":"61"},{"_id":"230"},{"_id":"429"},{"_id":"623"}],"user_id":"158","publication":"Photonic Computing: From Materials and Devices to Systems and Applications II","publisher":"SPIE","year":"2025","title":"Topology-optimized silicon nitride coupler for integrated single-photon emitters","citation":{"bibtex":"@inproceedings{Farheen_Chen_Chen_Kryvobok_Peana_Senichev_Shalaev_Boltasseva_Förstner_Kildishev_2025, title={Topology-optimized silicon nitride coupler for integrated single-photon emitters}, DOI={<a href=\"https://doi.org/10.1117/12.3065734\">10.1117/12.3065734</a>}, booktitle={Photonic Computing: From Materials and Devices to Systems and Applications II}, publisher={SPIE}, author={Farheen, Henna and Chen, Yuheng and Chen, Peigang and Kryvobok, Artem and Peana, Samuel and Senichev, Alexander and Shalaev, Vladimir M. and Boltasseva, Alexandra and Förstner, Jens and Kildishev, Alexander V.}, editor={Ni, Xingjie and Cai, Wenshan}, year={2025} }","mla":"Farheen, Henna, et al. “Topology-Optimized Silicon Nitride Coupler for Integrated Single-Photon Emitters.” <i>Photonic Computing: From Materials and Devices to Systems and Applications II</i>, edited by Xingjie Ni and Wenshan Cai, SPIE, 2025, doi:<a href=\"https://doi.org/10.1117/12.3065734\">10.1117/12.3065734</a>.","ieee":"H.
