TAILIEUCHUNG - Hybrid integrated nanophotonic silicon based - structures

The semiconducting single-walled carbon nanotubes (s-SWNTs) solution was prepared by polymer-sorted method and coupled with the confined modes in silicon slotted PhC cavities. The enhancement ratio of is obtained by comparing between the PL peaks at two confined modes of the cavity. The PL enhancement result of the integrated system shows the potential for the realization of on-chip nanoscale sources. | Communications in Physics Vol. 29 No. 4 2019 pp. 481-490 DOI 0868-3166 29 4SI 13855 HYBRID INTEGRATED NANOPHOTONIC SILICON-BASED STRUCTURES THI HONG CAM HOANG1 2 THANH BINH PHAM2 THUY VAN NGUYEN2 VAN DAI PHAM2 HUY BUI2 VAN HOI PHAM2 ELENA DURAN3 CARLOS RAMOS3 XAVIER LE ROUX3 LAURENT VIVIEN3 AND ERIC CASSAN3 1 University of Science and Technology of Hanoi Vietnam Academy of Science and Technology 18 Hoang Quoc Viet Cau Giay Hanoi Vietnam 2Institute of Materials Science Vietnam Academy of Science and Technology 18 Hoang Quoc Viet Cau Giay Hanoi Vietnam 3 Centre for Nanoscience and Nanotechnology CNRS Universite Paris-Sud Universite Paris-Saclay 10 Boulevard Thomas Gobert 91120 Palaiseau France Ĩ E-mail Received 3 June 2019 Accepted for publication 30 November 2019 Published 12 December 2019 Abstract. We report nanophotonic silicon-based devices for hybrid integration 1D photonic crystal PhC on optical fiber i. e. fiber Bragg grating FBG sensing probe integrated in fiber laser structure for chemical sensors and slotted planar 2D PhC cavity combined with carbon nanotube CNT towards light nanosources. The experiments have been carried out by integrating 1D PhC on optical fiber in fiber laser structure. This structure possesses many advantages including high resolution for wavelength shift high optical signal-to-noise ratio OSNR of about 50 dB the small full width at half-maximum FWHM of about nm therefore its accuracy is enhanced as well as the precision and capability are achieved for remote sensing. Low nitrate concentration in water from 0 to 80 ppm has been used to demonstrate its sensing ability in the experiment. The proposed sensor can work with good repeatability rapid response and its sensitivity can be obtained of X 10 3 nm ppm with the limit of detection LOD of 3 ppm. For 2D PhC cavity enhancement of photoluminescence of CNT emission is observed. The semiconducting single-walled carbon nanotubes s-SWNTs .
