Publication number: 20090257063Abstract: An adjustable two-dimensional lamellar grating system including a lamellar grating and a movable mirror disposed substantially parallel to one another, and an interferometer using the adjustable lamellar grating system. In one example, the lamellar grating includes a dielectric wafer having a dielectric wafer having a plurality of periodically spaced recesses formed therein, wherein the dielectric wafer has higher reflectivity at its surface facing the movable mirror than at a second opposing surface. In one example, the system also includes a mechanism for moving the mirror relative to the dielectric wafer.Type: ApplicationFiled: June 12, 2009Publication date: October 15, 2009Applicant: Polychromix CorporationInventors: Malcolm C. Smith, Michael A. Butler, Erik Deutsch

Patent number: 7505641Abstract: A waveguide-based sensor is disclosed that uses one or more grating patterns of a bioreceptor on a surface of the waveguide to provide a wavelength-specific sensor response without the requirement of labeling the target molecule or the bioreceptor. Furthermore, there is provided a biosensor that, at least to a first order, is insensitive to non-specific binding.Type: GrantFiled: August 17, 2006Date of Patent: March 17, 2009Assignee: Polychromix CorporationInventors: Stephen D. Senturia, Malcolm C. Smith, Michael A. Butler, David R. Day

Patent number: 7379241Abstract: An apparatus for processing electromagnetic radiation. The apparatus comprises a dielectric reflector, a plurality of ridges disposed on the dielectric reflector and a plurality of grooves disposed intermediate adjacent ridges to form a diffraction grating. Each of the ridges comprises a first dielectric material disposed on the dielectric reflector having a first index of refraction and a second dielectric material, having a second index of refraction different than the first index of refraction, disposed on the first dielectric material.Type: GrantFiled: December 8, 2005Date of Patent: May 27, 2008Assignee: Polychromix CorporationInventor: Malcolm C. Smith

Patent number: 7196789Abstract: A light processor (such as a spectrometer) providing wavelength equalization for a sample pathway and a reference pathway by actuation of a light amplitude modulator. A chemometric processor including a light amplitude modulator capable of performing chemical analysis by applying weights to wavelengths of light, thereby reducing the need for electronic post processing.Type: GrantFiled: January 6, 2004Date of Patent: March 27, 2007Assignee: Polychromix CorporationInventors: Stephen D. Senturia, Malcolm C. Smith

Patent number: 7139128Abstract: A reflective diffraction grating having grooves and ridges and providing high throughput efficiency in the minus-first diffraction order. All but the zeroth diffraction order and the minus-first diffraction order may be prevented from existence by directing the radiation onto the grating at an appropriate angle. The radiation having a TM polarization is eliminated from the zeroth order by destructive interference by appropriate selection of a the groove width of the grating, and radiation having a TE polarization is eliminated from the zeroth order by destructive interference by depositing an overcoat of an appropriate thickness. A dielectric material may be deposited in the grooves.Type: GrantFiled: January 6, 2004Date of Patent: November 21, 2006Assignee: Polychromix CorporationInventors: Malcolm C. Smith, Richard S. Payne

Patent number: 6985308Abstract: A demultiplexer for use in a wavelength-division multiplexed optical system including a first positive lens group, a negative lens group, and a second positive lens group in order from a dispersive element and a reflective element. In some embodiments the reflective element is a light modulator, such as an actuatable diffraction grating. In some embodiments the demultiplexer is a part of a dynamic channel equalizer. In embodiments having a light modulator, the modulation may occur during both a first pass and a second pass.Type: GrantFiled: May 28, 2003Date of Patent: January 10, 2006Assignee: Polychromix CorporationInventors: Malcolm C. Smith, Michael A. Butler, William C. Sweatt

Patent number: 6768589Abstract: A diffraction grating providing reduced polarization dependent loss. The elements of pixels of the diffraction grating are fixed or actuated such that some grating elements are actuated to correspond to a positive polarization dependent loss and others are actuated to correspond to a negative polarization dependent loss. The pixels may include multiples of three grating elements or multiples of four grating elements. An electrostatic beam structure providing increased actuation in a direction away from a substrate may be used in a diffraction grating providing reduced polarization dependent loss.Type: GrantFiled: December 23, 2002Date of Patent: July 27, 2004Assignee: Polychromix CorporationInventors: Erik R.
