Patent number: 11885681Abstract: A compact, portable Raman spectrometer makes fast, sensitive standoff measurements at little to no risk of eye injury or igniting the materials being probed. This spectrometer uses differential Raman spectroscopy and ambient light measurements to measure point-and-shoot Raman signatures of dark or highly fluorescent materials at distances of 1 cm to 10 m or more. It scans the Raman pump beam(s) across the sample to reduce the risk of unduly heating or igniting the sample. Beam scanning also transforms the spectrometer into an instrument with a lower effective safety classification, reducing the risk of eye injury. The spectrometer's long standoff range automatic focusing make it easier to identify chemicals through clear and translucent obstacles, such as flow tubes, windows, and containers. And the spectrometer's components are light and small enough to be packaged in a handheld housing or housing suitable for a small robot to carry.Type: GrantFiled: March 28, 2022Date of Patent: January 30, 2024Assignee: Pendar Technologies, LLCInventors: Daryoosh Vakhshoori, Romain Blanchard, Peili Chen, Masud Azimi, Tobias Mansuripur, Kalyani Krishnamurthy, Arran M.

Patent number: 7027686Abstract: A splitter/combiner system including directional couplers and phase shifts where some of the directional couplers are subdivided into shorter directional couplers, with 0° phase shifts between them. The system provides improved ease of design, and uniformity. The subdivided couplers also provide more accurate ratios between all the couplers in the splitter/combiner.Type: GrantFiled: November 8, 2002Date of Patent: April 11, 2006Assignee: Cambrius, Inc.Inventors: Tairan Wang, Gökhan Ulu

Publication number: 20060013551Abstract: An integrated planar waveguide system including at least two primary waveguides for light propagation and coupling, and two or more mirror-imaged symmetrization structures in close proximity to the primary waveguides in order to provide micro-process-equalization during etch, growth, annealing and reflow processes. The primary waveguides are designed to carry light signals. The symmetrization waveguide structures are designed so that all the trenches between primary waveguides are identical to the desired degree. At the same time, the symmetrization structures are designed to have minimal detrimental impact on the optical performance of the coupler.Type: ApplicationFiled: June 7, 2005Publication date: January 19, 2006Inventors: James Foresi, Tairan Wang, Jean-Francois Viens, Dale Fried, Mohammad Khan, Michael Lim, Anuradha Agarwal, Gokhan Ulu
