Ndị na-eme nchọpụta na Harvard School of Engineering and Applied Sciences. John A. Paulson (Harvard John A. Paulson School of Engineering and Applied Sciences - SEAS) bụ ndị mbụ n'ụwa na-eji laser semiconductor mepụta ọwa nkwukọrịta. Ngwakọ eletrọn-photonic ngwakọ na-eji laser na-ewepụta ma na-ebufe akara ngwa ndakwa nri ma nwee ike ibute otu ụbọchị n'ụdị nkwukọrịta ikuku na-eku ume ọhụrụ.
Ige Dean Martin na-eme ihe mejupụtara ya ama ama "Volare" site na onye na-ekwu okwu kọmputa nwere ike ịdị ka ihe nkịtị kpamkpam, ma mgbe ị maara na nke a bụ mgbasa ozi redio mbụ site na iji teknụzụ laser, ọ bụ ahụmahụ dị iche iche. Ngwaọrụ ọhụrụ ahụ, nke otu sitere na SEAS mepụtara, na-arụ ọrụ na-eji laser infrared, kewara n'ime oghere nke ugboro dị iche iche. Ọ bụrụ na a ot laser n'ịwa a doo na otu ugboro, dị ka violin na-akpọ kpọmkwem ndetu, mgbe ahụ ngwaọrụ kere ndị ọkà mmụta sayensị emits ọtụtụ ibé na dị iche iche frequencies, nke na-evenly kesara na iyi, dị ka ezé nke a ntutu mbo, nke nyere. aha mbụ maka ngwaọrụ ahụ - infrared laser-frequency comb ( comb laser infrared).
N'afọ 2018, ndị otu SEAS chọpụtara na "ezé" nke laser comb nwere ike na-adaba na ibe ya, na-eme ka electrons na oghere laser na-emegharị na ugboro ugboro microwave na redio. Eletrọd dị n'elu nke ngwaọrụ ahụ nwere oghere etched nke na-arụ ọrụ dị ka antenna dipole ma na-arụ ọrụ dị ka onye na-ebufe. Site n'ịgbanwe parampat nke laser (ịgbanwe ya), ndị otu ahụ nwere ike itinye data dijitalụ na radieshon microwave. A na-ebunye akara ngosi ahụ na ebe a na-anata ya, bụ ebe a na-ebunye ya site na antenna mpi, kọmpụta na-ehichapụ ma depụta ya.
Marco Piccardo, ọkà mmụta sayensị na-eme nchọpụta na SEAS na-ekwu, "Ngwaọrụ a niile jikọtara ọnụ nwere nnukwu nkwa maka nkwukọrịta ikuku." "Ọ bụ ezie na nrọ nke nkwukọrịta ikuku terahertz ka dị anya, nyocha a na-enye anyị ụzọ doro anya na-egosi ebe anyị kwesịrị ịga."
Na tiori, enwere ike iji transmitter laser dị otú ahụ na-ebufe akara na ugboro nke 10-100 GHz na ruo 1 THz, nke n'ọdịnihu ga-enye ohere ịnyefe data na ọsọ ọsọ ruo 100 Gbit/s.
