ʻO ROF fiber laser Polarization Modulation Fiber Polarization Controller

ʻO nā mea hoʻohana uila ROF Fiber Polarization Controllers. ʻO kēia huahana he mea hoʻokele polarization ikaika me nā kuleana waiwai kūʻokoʻa, hiki ke hoʻololi i ka polarization i ka wikiwiki kiʻekiʻe a i ka manawa maoli. Loaʻa iā ia nā hiʻohiʻona o ka poho hoʻokomo haʻahaʻa, liʻiliʻi liʻiliʻi, a me ke kiʻekiʻe o ka hoʻohui ʻana, a hoʻohana nui ʻia i nā laser fiber, fiber sensing, high-speed optical communication, a me ka quantum secure communication.

Hoʻokumu ʻia kēia huahana me kahi piezoelectric ʻekolu axis PZT, me kahi kaʻa kaʻa kaʻa hoʻokiʻekiʻe kiʻekiʻe-voltage i kūkulu ʻia, ʻaʻole koi i ka hoʻokomo uila kiʻekiʻe. Pono wale ia e hoʻomalu ʻia e kahi polokalamu Supervisory Control and Data Acquisition software e hoʻololi i ka mokuʻāina polarization i hāʻawi ʻia i kekahi mokuʻāina polarization ʻē aʻe i ka manawa maoli, a mālama i ka paʻa no kekahi mokuʻāina polarization. ʻO kāna hoʻolālā hoʻolālā fiber āpau e hana i kona hoʻokomo ʻana i ka nalowale <0.5dB a me ka hoʻihoʻi ʻana> 50dB.
