Electro-optic modulatorʻO ia ke kī nui e hoʻololi i ka hōʻailona laser mau me ka hoʻohana ʻana i ka ʻikepili, ka lekiō a me nā hōʻailona uaki.Loaʻa nā ʻano hana like ʻole o ka modulator.Ma o ka optical modulator, ʻaʻole hiki ke hoʻololi wale i ka ikaika o ka nalu māmā, akā hiki ke hoʻololi ʻia ka pae a me ke kūlana polarization o ka nalu māmā.ʻO nā modulator electro-optic i hoʻohana pinepine ʻia ʻo Mach-Zehndermea hoʻololi ikaikaanā mea modulators.
ʻO kaLiNbO3 mea hoʻololi ikaikahoʻohana nui ʻia i ka ʻōnaehana kamaʻilio optical kiʻekiʻe, ka ʻike laser a me nā ʻōnaehana ROF ma muli o ka hana electro-optic maikaʻi.ʻO ka moʻo R-AM e pili ana i ka MZ push-pull structure a me ka hoʻolālā X-cut, loaʻa nā hiʻohiʻona kino a me nā kemika, hiki ke hoʻohana ʻia ma nā hoʻokolohua hoʻokolohua a me nā ʻōnaehana ʻoihana.

Nā koi no ka lākiō hoʻopau kiʻekiʻe
1. Pono e loaʻa i ka lākiō hoʻopau kiʻekiʻe ka modulator System.ʻO ke ʻano o ka ʻōnaehana modulator e hoʻoholo i ka hiki ke hoʻokō ʻia ka lākiō hoʻopau loa.
2. E mālama ʻia ka polarization o ke kukui hoʻokomo modulator.Pili nā modulators i ka polarization.Hiki i ka polarization kūpono ke hoʻomaikaʻi i ka ratio extinction ma luna o 10dB.I nā hoʻokolohua lab, maʻamau ka mea e pono ai ka mea hoʻoponopono polarization.
3. ʻO nā mea hoʻoponopono pili pono.I kā mākou DC extinction ratio hoʻokolohua, 50.4dB extinction ratio ua loaʻa.ʻOiai ʻo ka ʻikepili o ka mea hana modulator e papa inoa wale i 40dB.ʻO ke kumu o kēia hoʻomaikaʻi ʻana ʻo ia ka holo wikiwiki ʻana o kekahi mau modulators.Hoʻopau nā mea hoʻoponopono hoʻopono ʻo Rofea R-BC-ANY i ka uila bias i kēlā me kēia 1 kekona e hōʻoia i ka pane wikiwiki.
Ua kālele ʻia ʻo ROF i nā kaapuni hoʻohui electro-optic a me nā ʻāpana no kahi ʻumi makahiki.Hana mākou i nā modulators integrated-optical hana kiʻekiʻe a hāʻawi i nā hoʻonā a me nā lawelawe hou no nā mea noiʻi ʻepekema a me nā ʻenekini ʻoihana.ʻO nā modulators o ka Rofea me ka uila haʻahaʻa haʻahaʻa a me ka nalo hoʻokomo haʻahaʻa i hoʻohana mua ʻia i ka puʻupuʻu kī quantum, nā ʻōnaehana radio-over-fiber, nā ʻōnaehana ʻike laser, a me ke kelepona ʻike o ka hanauna hou.
Hāʻawi pū mākou i nā modulators kūikawā he nui no ka hana maʻamau, e like me 1 * 4 array phase modulators, ultra-low Vpi, a me ultra-high extinction ratio modulators, i hoʻohana nui ʻia i nā kulanui a me nā kula.Hoʻohui, hana mākou i ka RF amplifier (modulator driver) a me BIAS controller, photonics detector etc.
I ka wā e hiki mai ana, e hoʻomau mākou i ka hoʻomaikaʻi ʻana i ka moʻo huahana e kū nei, e kūkulu i kahi hui ʻenehana loea, e hoʻomau i ka hāʻawi ʻana i nā mea hoʻohana i nā huahana kiʻekiʻe, hilinaʻi, holomua a me nā lawelawe ʻenehana.
