Patent number: 10545292Abstract: An optical waveguide circuit device includes: an optical waveguide circuit including a cladding layer formed on a substrate and made from silica-based glass, and an optical waveguide formed within the cladding layer and made from silica-based glass; heaters formed over the cladding layer and the optical waveguide and configured to heat the optical waveguide; wiring line electrode layers formed over the cladding layer, each of the wiring line electrode layers being coupled to a corresponding heater of the heaters and configured to allow electrical power to be supplied to the coupled heater; and an insulating layer covering the cladding layer, the heaters, and the wiring line electrode layers. The wiring line electrode layers adjacent to each other in a plan view are formed in different wiring layers. The wiring line electrode layers adjacent to each other in the same wiring layer are spaced by at least a predetermined distance.Type: GrantFiled: September 28, 2018Date of Patent: January 28, 2020Assignee: FURUKAWA ELECTRIC CO., LTD.Inventors: Masanori Takahashi, Yasuyoshi Uchida, Shintaro Yamasaki, Junichi Hasegawa

Patent number: 9417388Abstract: A spot-size-converting optical waveguide includes a core portion. A first core portion of the core portion has a first straight portion and a first tapered portion. The first straight portion extends in a direction, having width and height that are approximately constant in the direction, and the first tapered portion is continuous with the first straight portion and decreases in width and height toward a termination portion. A second core portion of the core portion has a straight-portion-coating portion, a tapered-portion-coating portion, and a second tapered portion, the straight-portion-coating portion covers the first straight portion, the tapered-portion-coating portion covers the first tapered portion continuously with the straight-portion-coating portion and decreases in width and height along the first tapered portion's shape, and the second tapered portion increases in width and height toward the direction. A refractive index of the second core portion is lower than that of the first core portion.Type: GrantFiled: December 7, 2015Date of Patent: August 16, 2016Assignee: FURUKAWA ELECTRIC CO., LTD.Inventors: Shintaro Yamasaki, Kazutaka Nara, Masanori Takahashi, Yasuyoshi Uchida

Organic el panel, panel-combined light emitting device, and method of manufacturing organic el panel
Patent number: 8917017Abstract: For organic EL panels with a hollow-sealed structure to meet the demand of flat or large displays, the inconvenience of contact of drying anent etc touching the organic EL elements in the sealed space is avoided. An organic EL panel includes a panel substrate, a light-emitting part with a plurality of organic EL elements having an anode, an organic layer and a cathode laminated on the panel substrate, and a sealing substrate configured to be bonded onto the panel substrate through an adhesive layer to seal the light-emitting part. The sealing substrate includes a supporting projection projecting toward the panel substrate. A supporting margin facing to the bottom face of the supporting projection is provided where the organic EL elements is not formed within a region of the light-emitting part on the panel substrate.Type: GrantFiled: March 8, 2010Date of Patent: December 23, 2014Assignees: Tohoku Pioneer Corporation, Mitsubishi Electric CorporationInventors: Zenichiro Hara, Satoru Kiridoshi, Suguru Nagae, Takanori Okumura, Shintaro Yamasaki, Yuji Saito, Yutaka Saito, Masashi Fukuzaki, Masami Kimura -
Publication number: 20120178334Abstract: A method of manufacturing an organic EL panel includes forming a light-emitting part having at least one organic EL element on a panel substrate, forming a concave portion for housing the light-emitting part on a sealing substrate, and sealing the light-emitting part by bonding the panel substrate and the sealing substrate together through an adhesive layer. A supporting projection projecting toward the panel substrate is formed while the concave portion is being formed, and a supporting margin facing the bottom face of the supporting projection is provided where the organic EL elements are not formed within a region of the light-emitting part on the panel substrate.Type: ApplicationFiled: March 15, 2012Publication date: July 12, 2012Applicants: MITSUBISHI ELECTRIC CORPORATION, TOHOKU PIONEER CORPORATIONInventors: Zenichiro Hara, Satoru Kiridoshi, Suguru Nagae, Takanori Okumura, Shintaro Yamasaki, Yuji Saito, Yutaka Saito, Masashi Fukuzaki, Masami Kimura
