Abstract: To measure homodyne interference with a CARS microscope, a supercontinuum beam is used as a light source. A supercontinuum beam is generated using a nonlinear optical fiber that has normal dispersion in which the coherence between pulses is maintained. As the phases of the interference components of detected beams are the same between pulses, it is possible to integrate the interference components and thus improve the signal-noise ratio.

Abstract: A system and method for reliably testing for toxic substances is described. Based on spectrographic means, the system embodies one or more types of spectrometers, designed for the detection of toxic elements such as lead, and alternatively designed for the detection of toxic compounds such as asbestos. By restricting the broad functionality common to a typical spectrometer, dramatic cost reductions can be made permitting the device to be cost-effectively manufactured and made available to the typical consumer. The device can be portable and incorporates safety systems to inhibit improper use.

Abstract: Techniques and mechanisms for a monolithic photonic integrated circuit (PIC) to provide spectrometry functionality. In an embodiment, the PIC comprises a photonic device, a first waveguide and a second waveguide, wherein one of the first waveguide and the second waveguide includes a released portion which is free to move relative to a substrate of the PIC.

In another embodiment, light from the first waveguide is variously diffracted by a grating of the photonic device during the metering cycle, where portions of the light are directed into the second waveguide. Different wavelengths of light diffracted into the second waveguide may be successively detected, for different positions of the released portion, to determine spectrometric measurements over a range of wavelength.
