Patent number: 7563635Abstract: In the present invention, an etching hole 21 is formed in a polysilicon film 14 as a cavity-wall member. Through the etching hole 21, hydrofluoric acid is injected, so as to dissolve a silicon oxide film 13, thereby forming a cavity 22. In the cavity 22, a detecting unit 12 of a sensor is in an exposed condition. Next, by sputtering, an Al film 16 is deposited in the etching hole 21 and on an upper face of a substrate. Thereafter, a portion of the Al film 16 positioned on the polysilicon film 14 is removed by etching back, thereby leaving only a metal closure 16a of Al which closes the etching hole. The sputtering step is performed under a pressure of 5 Pa or less, so that the pressure in the cavity can be held to be low.Type: GrantFiled: August 15, 2007Date of Patent: July 21, 2009Assignee: Panasonic CorporationInventors: Kimiya Ikushima, Hiroyoshi Komobuchi, Asako Baba, Mikiya Uchida

Patent number: 6879756Abstract: An optical delay line of a configuration in which a number of components such as a circulator and an optical coupler is reduced is to be provided. To this end, the optical delay line has a configuration in which, after an optical fiber diffraction grating having a core subjected to refractive index modulation and a cladding partly cleared of its outer circumference and an optical fiber having a cladding partly cleared of its outer circumference are brought close to each other so that the cores have mutually parallel directions of an optical axis to fabricate a directional coupler, both ends of the optical fiber are connected into an optical fiber loop. In this way, an optical delay line to generate a specific time delay for controlling optical signals can be provided in small dimensions and with a small number of components.Type: GrantFiled: February 13, 2003Date of Patent: April 12, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shinichi Wakabayashi, Hitomi Moriya, Yoshinori Takeuchi, Asako Baba

Publication number: 20040008939Abstract: There is provided a dispersion compensator that solves a problem of loss due to radiation mode and has a wide band and causes smaller insertion loss, and is compact in size and inexpensive. To achieve this, the dispersion compensator is constructed to comprise a fiber Bragg grating subjected to refractive index modulation to reflect lights of various wavelengths, wherein a core part of the fiber Bragg grating includes plural refractive index modulation parts that become continuously shorter in reflection wavelength toward a longitudinal direction from a light incidence side and are in positions different from each other in the longitudinal direction, and a discontinuous part, provided between the refractive index modulation parts, in which reflection wavelength shifts discontinuously to the long wavelength side. Light is inputted and outputted to and from the fiber Bragg grating by use of an optical circulator or the like.Type: ApplicationFiled: April 29, 2003Publication date: January 15, 2004Applicant: Matsushita Electric Industrial Co., Ltd.Inventor: Asako Baba
