Hoʻohālikelike o nā ʻōnaehana mea kaapuni hoʻohui photonic
Hōʻike ka Kiʻi 1 i ka hoʻohālikelike ʻana o nā ʻōnaehana waiwai ʻelua, indium Phosphorus (InP) a me ke silika (Si). ʻO ka rarity o ka indium e hoʻolilo iā InP i mea waiwai nui ma mua o Si. Ma muli o ka liʻiliʻi o ka ulu ʻana o ka epitaxial i nā kaʻapuni pili kilika, ʻoi aku ka kiʻekiʻe o ka hua o nā kaapuni pili kilika ma mua o nā kaapuni InP. I loko o nā kaapuni pili kilika, germanium (Ge), ka mea maʻamau i hoʻohana wale ʻia maMea ʻike kiʻi(nā mea ʻike kukui), pono ka ulu ʻana o ka epitaxial, ʻoiai ma nā ʻōnaehana InP, pono e hoʻomākaukau ʻia nā alakaʻi nalu passive e ka ulu ʻana o ka epitaxial. ʻO ka ulu ʻana o ka epitaxial e ʻoi aku ka nui o ka defect density ma mua o ka ulu ʻana o ka kristal hoʻokahi, e like me ka ingot kristal. Loaʻa i nā alakaʻi hawewe InP ka ʻokoʻa kikoʻī kikoʻī kiʻekiʻe ma ka transverse wale nō, ʻoiai ʻo nā alakaʻi hawewe kumu kiʻekiʻe he kiʻekiʻe ka ʻokoʻa ʻano hoʻohālikelike i ka transverse a me ka longitudinal, kahi e hiki ai i nā mea hana kilika ke hoʻokō i nā radii piko liʻiliʻi a me nā hale paʻa ʻē aʻe. Loaʻa i ka InGaAsP kahi ʻāpana hui pololei, ʻoiai ʻaʻole ʻo Si a me Ge. ʻO ka hopena, ʻoi aku ka maikaʻi o nā ʻōnaehana waiwai InP i nā ʻōlelo o ka pono laser. ʻAʻole paʻa a paʻa nā ʻokikene intrinsic o nā ʻōnaehana InP e like me nā oxide intrinsic o Si, silicon dioxide (SiO2). ʻOi aku ka ikaika o ka Silicon ma mua o InP, e ʻae ana i ka hoʻohana ʻana i nā nui wafer nui, ʻo ia hoʻi mai 300 mm (e hoʻonui koke ʻia i 450 mm) i hoʻohālikelike ʻia me 75 mm ma InP. InPmodulatorshilinaʻi maʻamau i ka hopena Stark quantum-confined, ʻo ia ka maʻalahi o ka wela ma muli o ka neʻe ʻana o ka ʻaoʻao ma muli o ka wela. ʻO ka ʻokoʻa, liʻiliʻi loa ka hilinaʻi wela o nā modulators-based silicon.

Manaʻo ʻia ka ʻenehana kiʻi kiʻi silikoni kūpono wale no nā huahana haʻahaʻa, pōkole, kiʻekiʻe (ʻoi aku ma mua o 1 miliona mau ʻāpana i kēlā me kēia makahiki). ʻO kēia no ka mea ua ʻae ʻia ka nui o ka nui o ka wafer e koi ʻia e hoʻolaha i ka mask a me nā kumukūʻai hoʻomohala, a ʻo iaʻenehana photonics silikaloaʻa i nā hemahema hana nui ma ke kūlanakauhale-a-kūlanakauhale a me nā noi huahana lōʻihi. ʻO ka ʻoiaʻiʻo naʻe, ʻo ka mea ʻē aʻe. Ma nā kumu kūʻai haʻahaʻa, pōkole, nā noi kiʻekiʻe, ʻo ka laser hoʻoheheʻe ʻia o ka ʻaoʻao (VCSEL) alaser-modulated pololei (DML laser): ʻO ka laser modulated pololei e hoʻokau i kahi koʻikoʻi hoʻokūkū nui, a ʻo ka nāwaliwali o ka ʻenehana photonic ma muli o ke silika ʻaʻole hiki ke hoʻohui maʻalahi i nā lasers i lilo i mea pōʻino nui. ʻO ka ʻokoʻa, ma ka metro, nā noi lōʻihi, ma muli o ka makemake no ka hoʻohui ʻana i ka ʻenehana photonics silicon a me ka hoʻoili hōʻailona kikohoʻe (DSP) pū kekahi (ʻo ia ka mea ma nā wahi wela wela), ʻoi aku ka maikaʻi o ka hoʻokaʻawale ʻana i ka laser. Eia kekahi, hiki i ka ʻenehana ʻike koʻikoʻi ke hana i nā hemahema o ka ʻenehana photonics silicon i kahi nui, e like me ka pilikia i ʻoi aku ka liʻiliʻi o ka pōʻeleʻele ma mua o ka photocurrent oscillator kūloko. I ka manawa like, he hewa nō hoʻi ka manaʻo he nui ka nui o ka wafer e pono ai e uhi i ka mask a me nā kumukūʻai hoʻomohala, no ka mea, hoʻohana ka ʻenehana photonics silicon i nā nui node i ʻoi aku ka nui ma mua o nā mea hoʻohui ʻoi loa metala oxide semiconductors (CMOS), no laila ʻoi aku ka maʻalahi o nā masks i koi ʻia a me nā holo hana.
