Patent number: 8531756Abstract: A method and apparatus is provided for processing an optical beam. The method includes spatially dispersing an optical beam received from an optical port into a plurality of wavelength components. The wavelength components are focused and at least one of the components is selectively directed to one of the optical ports by reflecting the focused wavelength component at least twice from a DMD before being directed to a selected one of the optical ports. A resolution of the focused wavelength component is optimized when it is reflected from the DMD a first or second time at the expense of the other time when it is reflected.Type: GrantFiled: September 15, 2011Date of Patent: September 10, 2013Assignees: Nistica, Inc., Fujikura Ltd.Inventors: Jefferson Wagener, Susumu Nakaya, Takaaki Ishikawa

Patent number: 8368987Abstract: Provided is an optical processing device including: a beam emission portion which includes a plurality of optical fibers; a dispersion element which disperses a beam emitted from one optical fiber of the plurality of optical fibers; a condenser lens which concentrates the beam passing through the dispersion element; and an optical path conversion optical system which converts an optical path of the beam passing through the condenser lens so that the beam is incident to one of the other optical fibers of the plurality of optical fibers. An optical axis of the condenser lens is inclined with respect to an optical axis direction from the beam emission portion to the optical path conversion optical system. The inclination angle is set so that a maximum difference in focal depth of a plurality of beams having different wavelengths obtained by the dispersion element becomes smaller.Type: GrantFiled: September 15, 2011Date of Patent: February 5, 2013Assignees: Nistica, Inc., Fujikura, Ltd.Inventors: Seungbum Woo, Jefferson Wagener, Susumu Nakaya, Takaaki Ishikawa

Publication number: 20070003186Abstract: An optical switch is provided which includes a plurality of input/output ports for receiving one or more wavelength component(s) of an optical signal. The optical switch also includes an optical arrangement that directs the wavelength component to any given one of the plurality of input/output ports. The given input/output port may be selected from among any of the plurality of input/output ports. If the optical signal includes a plurality of wavelength components, the optical arrangement includes at least one wavelength selective element such as a thin film filter. The wavelength selective element selects one of the wavelength components from among the plurality of wavelength components. The optical arrangement also includes a plurality of optical elements each associated with one of the wavelength selective elements.Type: ApplicationFiled: June 17, 2004Publication date: January 4, 2007Inventors: Jefferson Wagener, Christopher Koeppen, Allan Schweitzer, Thomas Strasser
