Abstract: Methods and systems for performing simultaneous spectroscopic measurements of semiconductor structures over a broad range of angles of incidence (AOI), azimuth angles, or both, are presented herein. Spectra including two or more sub-ranges of angles of incidence, azimuth angles, or both, are simultaneously measured over different sensor areas at high throughput. Collected light is linearly dispersed across different photosensitive areas of one or more detectors according to wavelength for each subrange of AOIs, azimuth angles, or both. Each different photosensitive area is arranged on the one or more detectors to perform a separate spectroscopic measurement for each different range of AOIs, azimuth angles, or both. In this manner, a broad range of AOIs, azimuth angles, or both, are detected with high signal to noise ratio, simultaneously. This approach enables high throughput measurements of high aspect ratio structures with high throughput, precision, and accuracy.

Abstract: A center wavelength of first pulsed light (exciting pulsed light) is variable, and a pulse rate of the first pulsed light coincides with an integer multiple of a free spectral interval of an optical oscillator at a center wavelength of second pulsed light (signal pulsed light or idler pulsed light). A center wavelength of a nonlinear gain generated by a nonlinear optical medium is made approximately coincident with the center wavelength of the second pulsed light.

Abstract: A photoconductive device that includes a semiconductor substrate, an antenna assembly, and a photoconductive assembly with one or more plasmonic contact electrodes. The photoconductive assembly can be provided with plasmonic contact electrodes that are arranged on the semiconductor substrate in a manner that improves the quantum efficiency of the photoconductive device by plasmonically enhancing the pump absorption into the photo-absorbing regions of semiconductor substrate. In one exemplary embodiment, the photoconductive device is arranged as a photoconductive source and is pumped at telecom pump wavelengths (e.g., 1.0-1.6 μm) and produces milliwatt-range power levels in the terahertz (THz) frequency range.

Abstract: A resin identification device capable of measuring samples having various shapes is provided. The resin identification device includes a Fourier transform infrared spectrophotometer (FTIR), and sample placing plates 31 and 32 having an opening 33. The FTIR includes: an infrared light source section 10, irradiating a sample S with infrared light; an infrared light detection section 20, detecting light intensity information of the infrared light reflected from the sample S; and a control section 50, obtaining the light intensity information. By replacement of the sample S in a predetermined position so as to block off the opening 33, the infrared light source section 10 irradiates infrared light on a lower surface of the sample S, and the infrared light detection section 20 detects the light intensity information of the infrared light reflected by the lower surface of the sample S.

Abstract: A method and a system for measuring an optical asynchronous sample signal. The system for measuring an optical asynchronous sampling signal comprises a pulsed optical source capable of emitting two optical pulse sequences with different repetition frequencies, a signal optical path, a reference optical path, and a detection device. Since the optical asynchronous sampling signal can be measured by merely using one pulsed optical source, the complexity and cost of the system are reduced. A multi-frequency optical comb system using the pulsed optical source and a method for implementing the multi-frequency optical comb are further disclosed.

Abstract: A small size, robust stimulated Raman scattering (SRS) spectrophotometer system for industrial, medical and field use, exhibiting high SNR, high resolution and very short acquisition times. The architecture of the system allowing for such features comprises three main elements: (1). Use of a narrow range tunable pump laser and an array of fixed wavelength lasers to produce the wavelength differences as required to generate the SRS (Raman) spectrum; (2). Application of analog signal processing, prior to the digital conversion, in order to obtain higher resolution and SNR; (3). Use of relatively inaccurate or unstable laser sources coupled to calibration samples, followed by various calibration methods to compensate for system instabilities, such as wavelength drift, laser inaccuracies, and variations in the optical components/elements of the system.
