Optoelectronictxoj kev koom ua ke
Kev koom ua ke ntawmkev siv photonicthiab cov khoom siv hluav taws xob yog ib kauj ruam tseem ceeb hauv kev txhim kho lub peev xwm ntawm cov txheej txheem ua cov ntaub ntawv, ua kom cov nqi hloov pauv cov ntaub ntawv sai dua, kev siv hluav taws xob tsawg dua thiab cov qauv tsim khoom siv me dua, thiab qhib cov cib fim tshiab rau kev tsim qauv. Cov txheej txheem kev sib koom ua ke feem ntau muab faib ua ob pawg: kev sib koom ua ke monolithic thiab kev sib koom ua ke ntau lub nti.
Kev koom ua ke ntawm monolithic
Kev sib koom ua ke ntawm cov khoom siv photonic thiab cov khoom siv hluav taws xob ntawm tib lub substrate, feem ntau yog siv cov ntaub ntawv thiab cov txheej txheem sib xws. Txoj hauv kev no tsom mus rau kev tsim kom muaj kev sib txuas lus zoo ntawm lub teeb thiab hluav taws xob hauv ib lub chip.
Cov txiaj ntsig:
1. Txo qhov kev poob ntawm kev sib txuas: Kev tso cov photons thiab cov khoom siv hluav taws xob ze ze ua rau txo qhov kev poob ntawm cov teeb liab uas cuam tshuam nrog kev sib txuas tawm ntawm lub chip.
2, Kev ua tau zoo dua: Kev sib koom ua ke nruj dua tuaj yeem ua rau kev hloov pauv cov ntaub ntawv sai dua vim yog txoj kev teeb liab luv dua thiab txo qis latency.
3, Qhov me me dua: Kev sib koom ua ke monolithic tso cai rau cov khoom siv compact heev, uas yog qhov tshwj xeeb tshaj yog rau cov ntawv thov txwv qhov chaw, xws li cov chaw khaws ntaub ntawv lossis cov khoom siv tes ua.
4, txo kev siv hluav taws xob: tshem tawm qhov xav tau cov pob khoom sib cais thiab kev sib txuas ntev, uas tuaj yeem txo qhov xav tau hluav taws xob.
Kev Sib Tw:
1) Kev sib xws ntawm cov khoom siv: Kev nrhiav cov khoom siv uas txhawb nqa ob qho tib si cov electrons zoo thiab cov haujlwm photonic tuaj yeem nyuaj vim tias lawv feem ntau xav tau cov khoom sib txawv.
2, kev sib raug zoo ntawm cov txheej txheem: Kev koom ua ke ntawm ntau yam kev tsim khoom ntawm cov khoom siv hluav taws xob thiab cov photons ntawm tib lub substrate yam tsis muaj kev puas tsuaj rau kev ua tau zoo ntawm ib qho khoom yog ib txoj haujlwm nyuaj.
4, Kev tsim khoom nyuaj: Qhov kev ntsuas siab uas xav tau rau cov qauv hluav taws xob thiab photononic ua rau qhov nyuaj thiab tus nqi ntawm kev tsim khoom nce ntxiv.
Kev koom ua ke ntawm ntau lub chips
Txoj hauv kev no tso cai rau kev ywj pheej ntau dua hauv kev xaiv cov ntaub ntawv thiab cov txheej txheem rau txhua txoj haujlwm. Hauv kev koom ua ke no, cov khoom siv hluav taws xob thiab photonic los ntawm cov txheej txheem sib txawv thiab tom qab ntawd tau sib sau ua ke thiab muab tso rau ntawm ib pob khoom lossis substrate (Daim Duab 1). Tam sim no cia peb teev cov hom kev sib txuas ntawm cov chips optoelectronic. Kev sib txuas ncaj qha: Cov txheej txheem no cuam tshuam nrog kev sib cuag ncaj qha thiab kev sib txuas ntawm ob qhov chaw planar, feem ntau yog pab txhawb los ntawm cov rog sib txuas molecular, cua sov, thiab siab. Nws muaj qhov zoo ntawm kev yooj yim thiab kev sib txuas poob qis heev, tab sis xav tau qhov sib dhos thiab huv si. Fiber / grating coupling: Hauv cov phiaj xwm no, cov fiber lossis fiber array tau sib dhos thiab sib txuas rau ntug lossis qhov chaw ntawm photonic chip, tso cai rau lub teeb kom txuas rau hauv thiab tawm ntawm lub chip. Lub grating kuj tseem siv tau rau kev sib txuas ntsug, txhim kho qhov ua tau zoo ntawm kev xa lub teeb ntawm lub photonic chip thiab cov fiber sab nraud. Los ntawm-silicon qhov (TSVs) thiab micro-bumps: Los ntawm-silicon qhov yog cov kev sib txuas ntsug los ntawm silicon substrate, tso cai rau cov chips kom raug teeb tsa hauv peb qhov ntev. Ua ke nrog cov ntsiab lus me me-convex, lawv pab ua kom tiav kev sib txuas hluav taws xob ntawm cov khoom siv hluav taws xob thiab photonic hauv cov qauv teeb tsa, tsim nyog rau kev sib koom ua ke siab. Txheej nruab nrab ntawm qhov muag: Txheej nruab nrab ntawm qhov muag yog ib lub substrate sib cais uas muaj cov waveguides optical uas ua haujlwm ua tus neeg nruab nrab rau kev xa cov teeb liab optical ntawm cov chips. Nws tso cai rau kev sib phim meej, thiab ntxiv passivecov khoom siv kho qhov muagtuaj yeem sib xyaw ua ke rau kev sib txuas yooj yim dua. Kev sib txuas sib xyaw: Cov thev naus laus zis sib txuas siab heev no sib xyaw ua ke kev sib txuas ncaj qha thiab cov thev naus laus zis micro-bump kom ua tiav kev sib txuas hluav taws xob siab ntawm cov chips thiab cov khoom siv optical zoo. Nws yog qhov tshwj xeeb tshaj yog rau kev sib koom ua ke optoelectronic ua tau zoo. Kev sib txuas solder bump: Zoo ib yam li kev sib txuas flip chip, solder bumps yog siv los tsim kev sib txuas hluav taws xob. Txawm li cas los xij, hauv cov ntsiab lus ntawm kev sib koom ua ke optoelectronic, yuav tsum tau them sai sai rau kev zam kev puas tsuaj rau cov khoom photonic los ntawm kev ntxhov siab thermal thiab tswj kev sib dhos optical.
Daim Duab 1:: Electron/photon chip-to-chip Bonding scheme
Cov txiaj ntsig ntawm cov kev qhia no yog qhov tseem ceeb: Raws li lub ntiaj teb CMOS txuas ntxiv ua raws li kev txhim kho hauv Moore's Law, nws yuav ua tau kom hloov kho txhua tiam ntawm CMOS lossis Bi-CMOS mus rau hauv lub silicon photonic chip pheej yig, sau cov txiaj ntsig ntawm cov txheej txheem zoo tshaj plaws hauv photonics thiab electronics. Vim tias photonics feem ntau tsis xav tau kev tsim cov qauv me me (qhov loj me ntawm kwv yees li 100 nanometers yog qhov ib txwm muaj) thiab cov khoom siv loj dua piv rau transistors, kev txiav txim siab txog kev lag luam yuav thawb cov khoom siv photonic kom raug tsim tawm hauv cov txheej txheem sib cais, sib cais los ntawm txhua yam khoom siv hluav taws xob siab heev uas xav tau rau cov khoom kawg.
