Patent number: 7809217Abstract: In a polarization-independent light control element operable at low voltage, optical waveguides are provided in an X-cut first substrate and control electrodes are disposed thereabove. Optical waveguides are provided in a Z-cut second substrate and control electrodes are disposed thereabove. The control electrodes of the first and second substrates are connected in series to each other in the propagation direction of light. This allows a transverse electric component and a transverse magnetic component to be efficiently controlled because of the incorporation of high electro-optical effects of the optical waveguides of the first substrate on the transverse electric component and high electro-optical effects of the optical waveguides of the second substrate on the transverse magnetic component.Type: GrantFiled: July 20, 2009Date of Patent: October 5, 2010Assignee: Murata Manufacturing Co., Ltd.Inventors: Yasuhiro Kuratani, Hideya Horiuchi

Patent number: 7194793Abstract: A method for adjusting a frequency characteristic of an edge reflection type surface acoustic wave device includes the step of obtaining a frequency characteristic of an edge reflection type surface acoustic wave device having a piezoelectric substrate. The edge reflection type surface acoustic wave device has a pair of edges of the piezoelectric substrate which define a predetermined distance therebetween. The piezoelectric substrate is cut at a position which defines a distance that is shorter than the predetermined distance when a final frequency characteristic of the edge reflection type surface acoustic wave device is to be higher than the obtained frequency characteristic. The piezoelectric substrate is cut at a position which defines a distance that is longer than the predetermined distance when a final frequency characteristic of the edge reflection type surface acoustic wave device is to be lower than the obtained frequency characteristic.Type: GrantFiled: May 13, 2004Date of Patent: March 27, 2007Assignee: Murata Manufacturing Co., Ltd.Inventors: Michio Kadota, Yasunori Takakuwa, Seigo Hayashi, Junya Ago, Hideya Horiuchi, Mamoru Ikeura
