Ihe ọhụrụ na-eme naIhe nhazi LiNbO3
N'oge na-adịbeghị anya, ndị nchọpụta China ewepụtala patent mepụtara isi ihe na teknụzụ mkpọchi ugboro ole laser PDH. Sistemụ mkpọchi ugboro ole laser PDH dabere na SOA (Semiconductor Optical Amplifier) na-abụghị ahịrị iji mepụta ihe mgbochi akụkụ. Patent a na-achọ idozi ọtụtụ isi ihe mgbu dị na sistemụ mkpọchi ugboro ole laser PDH (Pound-Drever-Hall) ọdịnala n'ihi ojiji nke lithium niobate (LiNbO3 modulator) na ndị ọzọ.ihe na-eme ka electro-optic modulator dị.
1. Isi nsogbu nke ngwọta ọdịnala gụnyere:
1.1 Ọnụ ego dị elu na nhazi dị mgbagwoju anya: Ndị na-eme ka electro-optic modulators na-arụ ọrụ nke ọma chọrọ sekit RF dị mgbagwoju anya na nke na-anaghị adọrọ mmasị.
1.2 Mmetụta gburugburu ebe obibi: Na-enwe mmetụta maka mgbanwe okpomọkụ na nrụgide, na-enwekarị nsogbu ọnọdụ polarization.
1.3 Mmetụta nke mgbanwe oke olu (RAM): Nke a na-akpata nsogbu DC nke mgbaàmà njehie, na-eduga na mgbanwe nke ebe mkpọchi laser ma na-emetụta nkwụsi ike ogologo oge nke sistemụ ahụ.
2. Ngwọta ọhụrụ nke ndị otu nyocha ahụ tụrụ aro bụ:
Hapụ ihe modulator electro-optic ọdịnala kpamkpam ma were atụmatụ mmekorita nkeamplifier ngwa anya semiconductor(SOA amplifier) jikọtara ya na mgbanwe ugboro ugboro acousto-optic abụọ. Ụkpụrụ ọrụ kpọmkwem bụ: Mgbe e kewara laser mkpụrụ ahụ, a na-agbanwe ya kpọmkwem ugboro ugboro site na mgbanwe ugboro ugboro acousto-optic abụọ, na-emepụta ọdịiche ugboro ugboro, wee jikọta ụzọ ìhè abụọ ahụ ma gbanye ya n'ime amplifier SOA na steeti saturation gain. Site na iji mmetụta ndị na-abụghị ahịrị dị ka ngwakọta ebili mmiri anọ (FWM) nkeMkpọlite SOA, a na-emepụta akara multi-sideband dị mkpa maka mkpọchi ugboro PDH nke ọma.
3. Teknụzụ a na-eweta uru arụmọrụ ndị a na-akpata nsogbu:
3.1 Imeri nsogbu RAM ma nweta nkwụsi ike ogologo oge dị elu: Ngwaọrụ amplifier SOA (nke a na-ejikarị na ngwugwu urukurubụba) na-ejikọta njikwa okpomọkụ ma na-enweghị mmetụta dị ukwuu na nsogbu gburugburu ebe obibi, na-ezere nsogbu RAM site na usoro anụ ahụ ma na-enweta izi ezi nke ogologo oghere karịa 5×10¹¹¹/ụbọchị.
3.2 Njiko nke eriri akụkụ, mmụba dị ukwuu na oke mgbama-na-mkpọtụ: Site n'ịchịkwa oke mgbanwe nke ndị na-agbanwe ugboro ugboro acousto-optic abụọ (100 MHz – 200 MHz) site na oscillators abụọ na-achịkwa voltaji (VCO), enwere ike ijikọ oge ugboro nke eriri akụkụ emepụtara nke ọma na oke spectral free (FSR) nke oghere ntụaka, si otú a na-eme ka oke mgbama-na-mkpọtụ nke akara njehie dịkwuo mma nke ukwuu.
3.3 Mbelata ọnụ ahịa na mmezi arụmọrụ, nke na-enyere aka ime ka sistemụ dị obere: Na-enweghị ihe modulator electro-optic dị oke ọnụ na sekit dị mgbagwoju anya, ihe na-eme ka SOA optical amplifier chọrọ naanị draịva ọkụ dị mfe, na-eme ka sistemụ ahụ dum dịkwuo obere, dị ala na ọnụ ahịa, ma dabara adaba maka ngwa laser mpụga na obere nhazi.
3.4 Olileanya sara mbara nke itinye n'ọrụ na mkpa ahịa nke teknụzụ a gụnyere:
Elekere anya nke oghere na ụgbọala: Njirimara ya nke igbochi nsogbu na-emezu ihe achọrọ nke ubi ụgbọ elu na nke ụgbọala na-enweghị onye ọrụ.
Igwe ihe nrịbama nke quantum na ihe ndị na-eme ka atọm dị oyi: Enwere ike iji ya mee nchọpụta ala dị oke mma na ịnyagharịa mmiri n'okpuru mmiri.
Nchọpụta eriri dị elu na radar usoro nhazi (LiDAR): Nwere ike inye isi mmalite ìhè dị warara nke ukwuu, nke na-enweghị ntụgharị.
N'okpuru usoro nke mgbanwe quantum nke abụọ zuru ụwa ọnụ na obere ihe mmetụta quantum, ọchịchọ ahịa maka modulu modulu laser nke a na-achịkwa onwe ya, nke dị ọnụ ala, na nke kwụsiri ike ugboro ugboro amụbaala nke ukwuu, teknụzụ patent a na-agbasokwa usoro ahịa a kpọmkwem.
