ʻO ka hopena electro-optical e pili ana i ka hopena o ka loli ʻana o ka refractive index o kahi mea ke hoʻopili ʻia kahi kahua uila. ʻElua ʻano nui o ka hopena electro-optical, ʻo kekahi ka hopena electro-optical mua, i ʻike ʻia hoʻi ʻo ka hopena Pokels, e pili ana i ka loli linear o ka refractive index mea me ke kahua uila i hoʻopili ʻia. ʻO kekahi ka hopena electro-optical lua, i ʻike ʻia hoʻi ʻo ka hopena Kerr, kahi e kūlike ai ka loli o ka refractive index o ka mea i ka huinahā o ke kahua uila. Hoʻokumu ʻia ka hapa nui o nā modulators electro-optical ma ka hopena Pokels. Me ka hoʻohana ʻana i ka modulator electro-optic, hiki iā mākou ke hoʻololi i ke ʻano o ke kukui i komo mai, a ma ke kumu o ka modulation phase, ma o kahi hoʻololi, hiki iā mākou ke hoʻololi i ka ikaika a i ʻole ka polarization o ke kukui.

Aia kekahi mau ʻano hana kuʻuna like ʻole, e like me ka mea i hōʻike ʻia ma ke Kiʻi 2. ʻO (a), (b) a me (c) he mau ʻano hana modulator hoʻokahi me ke ʻano maʻalahi, akā ua kaupalena ʻia ka laulā laina o ka hui alapine optical i hana ʻia e ka bandwidth electro-optical. Inā koi ʻia kahi hui alapine optical me ke alapine hana hou kiʻekiʻe, pono ʻelua a ʻoi aku paha nā modulators ma ka cascade, e like me ka mea i hōʻike ʻia ma ke Kiʻi 2(d)(e). ʻO ke ʻano hope loa o ke ʻano hana e hana ai i kahi hui alapine optical ua kapa ʻia ʻo ia he resonator electro-optical, ʻo ia ka modulator electro-optical i kau ʻia i loko o ka resonator, a i ʻole hiki i ka resonator ponoʻī ke hana i kahi hopena electro-optical, e like me ka mea i hōʻike ʻia ma ke Kiʻi 3.

KII. 2 He mau mea hana hoʻokolohua no ka hana ʻana i nā hui alapine optical ma muli onā mea hoʻololi electro-optic

03 Nā ʻano o ka hoʻohuihui alapine optical modulation electro-optic

Pōmaikaʻi mua: hiki ke hoʻololi ʻia

ʻOiai ʻo ke kumu kukui he laser ākea ākea hiki ke hoʻololi ʻia, a he bandwidth alapine hana ko ka modulator electro-optical, hiki ke hoʻololi ʻia ke alapine o ka huila alapine optical modulation electro-optical. Ma waho aʻe o ke alapine hiki ke hoʻololi ʻia, ʻoiai hiki ke hoʻololi ʻia ka hanauna nalu o ka modulator, hiki ke hoʻololi ʻia ke alapine hana hou o ka huila alapine optical hopena. He pono kēia i loaʻa ʻole i nā huila alapine optical i hana ʻia e nā lasers mode-locked a me nā micro-resonators.

Pōmaikaʻi ʻelua: alapine hana hou

ʻAʻole wale ka loli o ka wikiwiki o ka hana hou ʻana, akā hiki ke hoʻokō ʻia me ka ʻole o ka hoʻololi ʻana i nā lako hoʻokolohua. ʻO ka laulā laina o ka electro-optic modulation optical frequency comb e like me ka modulation bandwidth, ʻo ka bandwidth modulator electro-optic kalepa maʻamau he 40GHz, a ʻo ka electro-optic modulation optical frequency comb repetition frequency hiki ke ʻoi aku ma mua o ka optical frequency comb bandwidth i hana ʻia e nā ʻano hana ʻē aʻe āpau koe wale nō ka micro resonator (hiki ke hiki i 100GHz).

Pōmaikaʻi 3: hoʻoponopono spectral

Ke hoʻohālikelike ʻia me ka kāhili optical i hana ʻia e nā ʻano ʻē aʻe, ua hoʻoholo ʻia ke ʻano o ka disc optical o ka kāhili optical electro-optic modulated e kekahi mau kekelē o ke kūʻokoʻa, e like me ka hōʻailona alapine lekiō, ka voltage bias, ka polarization hanana, a me nā mea ʻē aʻe, hiki ke hoʻohana ʻia e kāohi i ka ikaika o nā kāhili like ʻole e hoʻokō ai i ke kumu o ke ʻano spectral.

04 Ka hoʻohana ʻana o ka electro-optic modulator optical frequency comb

I ka hoʻohana pono ʻana o ka electro-optic modulator optical frequency comb, hiki ke hoʻokaʻawale ʻia i nā spectra comb hoʻokahi a me ka pālua. He haiki loa ka laina o kahi spectrum comb hoʻokahi, no laila hiki ke hoʻokō ʻia ka pololei kiʻekiʻe. I ka manawa like, i hoʻohālikelike ʻia me ka optical frequency comb i hana ʻia e ka laser mode-locked, ʻoi aku ka liʻiliʻi o ka hāmeʻa o ka electro-optic modulator optical frequency comb a ʻoi aku ka maikaʻi o ka hoʻonohonoho ʻana. Hoʻopuka ʻia ka spectrometer comb pālua e ka hoʻopilikia ʻana o ʻelua mau combs hoʻokahi kūlike me nā alapine hana hou ʻokoʻa iki, a ʻo ka ʻokoʻa i ka alapine hana hou ʻana ʻo ia ka laina o ka spectrum comb interference hou. Hiki ke hoʻohana ʻia ka ʻenehana optical frequency comb i ke kiʻi optical, ranging, ana mānoanoa, calibration mea hana, arbitrary waveform spectrum shaping, radio frequency photonics, kamaʻilio mamao, optical stealth a pēlā aku.

Kiʻi 4. Ke ʻano hoʻohana o ka hui alapine optical: Ke lawe nei i ke ana ʻana o ka ʻikepili pōkā wikiwiki kiʻekiʻe ma ke ʻano he laʻana
