Using a full modal vector model based on the finite-element method and anisotropic perfectly matched layers absorbing boundary conditions.\r In this paper, we design an ultra-broadband light source at 1060 nm for OCT application using a highly nonlinear octagonal photonic Crystal fiber. We show that it is possible to design a fiber with simply structure which has highly nonlinear and nearly zero dispersion over low OCT optical band by optimizing air hole diameter of ring and pitch. Structure of proposed PCFs with 5 air hole rings has an octagonal structure. This PCFs contains air holes in the cladding arranged in a stable array, where A is the center-to-center spacing between the air holes, di is the air hole diameter, d/A is the normalized diameters of the air holes in the cladding. The background material of PCF is pure silica with refractive index of 1.45, simultaneously doped Fluorite in core center with diameter dcore. This fiber has 5 air hole rings, diameter of inner ring air hole is d1 diameters of four outer four air hole rings correspond d2, d3, d4, d5, and hole-to-hole spacing pitch A.\r The nearly zero dispersion can be obtained by a suitable design of these parameters d1; d2; d3; d4, d5 and A. The parameters for calculation are Gamma = 152 (W-l.km-l), D =-0.08519 (ps/(mn.km), β2 = 0.048 (ps2-/km) and β3 = 0.000045 (ps3/km), Figure 2 shows spectral properties of the proposed PCF obtained where the fiber length is 140 m and the peak optical power of the incident pulse is l0W, TFWHM = 1 ps. Spectral Bandwidth is found at 175 nm at 3 dB bandwidth. The coherence length 1 and resolution lr, in biomedical tissue can be obtained. It is found that:l,=2.83 ɳm 1r, = 1.96 ɳm at 1060 nm with ntissue,= 1.44 at 1060 nm center wavelenght.\r In conclusion, the proposed PCFs may be suitable for chromatic dispersion management applications as a chromatic dispersion controller, also as an excellent candidate for nonlinear optical systems when can use for super continuum generation which useful in OCT application with high resolution optical image, provide the extremely apparent picture in dental capturing."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Highly Nonlinear"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Ultra-Broadband light source at 1060NM using highly nonlinear octagonal photonic crystal fiber.pdf", "filesize": [{"value": "1096 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1096000.0, "url": {"url": "https://meral.edu.mm/record/2005/files/Ultra-Broadband light source at 1060NM using highly nonlinear octagonal photonic crystal fiber.pdf"}, "version_id": "2c55bae4-c038-4e3b-a764-2506ebb398cb"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "8th AUN/SEED-Net Regional Conference on Electrical and Electronics Engineering"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Huy, Dam Quang"}, {"subitem_authors_fullname": "Hai, Nguyen Hoang"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Other"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Other"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2015"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://uyr.uy.edu.mm/handle/123456789/399"}, "item_title": "ULTRA-BROADBAND LIGTH SOURCE AT l060NM USING HIGHLY NONLINEAR OCTAGONAL PHOTONIC CRYSTAL FIBER", "item_type_id": "21", "owner": "1", "path": ["1582967549708"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000002005", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "2005", "relation": {}, "relation_version_is_last": true, "title": ["ULTRA-BROADBAND LIGTH SOURCE AT l060NM USING HIGHLY NONLINEAR OCTAGONAL PHOTONIC CRYSTAL FIBER"], "weko_shared_id": -1}
