Abstract: An apparatus for shared optical performance monitoring (OPM) is provided. A wavelength sensitive device receives light at an input port and routes it wavelength selectively to a set of output ports. To perform optical performance monitoring on the output ports, a monitoring component of each output signal is extracted, and these monitoring components are then combined. A single OPM function is then performed on the combined signal. However, with knowledge of the wavelengths that were included in each output signal, a virtual OPM function can be realized for each output port. The per port functionality can include total power per port, power per wavelength per port, variable optical attentuation, dynamic gain equalization, the latter two examples requiring feedback.

Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin (m theta + p pi /4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by corresponding filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.

The light source provides lights having a wide frequency region with a single mode optical fiber cable. The beam isolator transmits the lights provided by the light source to a single direction through the single mode optical fiber cable and blocks the transmission of the lights to an opposite direction. The optical coupler divides input lights transmitted through the optical fiber cable into two or more output light or joins two or more input lights as one output optical signal. The optical filter receives one output light from the optical coupler and use an optical fiber ferrule and transmits lights of a specific frequency by a WDM(Wavelength Division Multiplexing) and reflect the lights of a different frequency. The optical spectrometer receives the lights of the specific frequency reflected by the optical fiber bragg grating existed on the single mode optical fiber cable and the lights including optical frequency grating signals being reflected by the optical filter, thereby measuring optical spectrums of the two lights at the same time.

Abstract: Methods and apparatus for measuring an electromagnetic radiation response property associated with a substrate (210) and calibrating an electromagnetic measurement device (100) are disclosed. The methods and apparatus generate electromagnetic waves and capture a portion of the generated waves after the waves pass through a first polarized filter (236), reflect from a substrate (210), and pass through a second polarized filter (204) arranged in a cross polar arrangement with respect to the first polarized filter. In addition, the apparatus captures electromagnetic waves that pass through an attenuating filter (206) and reflect from one or more calibration standards (208). Digital data is determined from the captured electromagnetic waves. The digital data is used to recalibrate the apparatus.

Abstract: An optoelectronic module operable to acquire distance data and spectral data includes an array of demodulation pixels and an array of spectral filters. The demodulation pixels can possess an intrinsic wavelength-dependent sensitivity, wherein the intrinsic wavelength-dependent sensitivity can be offset by an intensity balancing micro-lens array in some cases. In some cases, the intrinsic wavelength-dependent sensitivity can be offset by a combined filter array, while in other cases the intrinsic wavelength-dependent sensitivity can be offset by an intensity balancing filter array. Still in other cases, the demodulation pixels can be operable in such as to offset the intrinsic wavelength-dependent sensitivity.

Abstract: A spectrometer (100) for optically characterizing a species in the ultraviolet and/or visible wavelength range is described. The spectrometer comprises a filter (110) for reducing or blocking a spectral portion of an impinging radiation and a detector (120) adapted for distinctively detecting spectral components of radiation impinging on a sensor surface. The filter (110) is directly mounted on a sensor surface of the detector and is a shaped filter having (110) a shape for partly covering the detector surface and partly leaving the detector surface open, the filter being adapted for blocking a spectral portion of impinging radiation at the covered sensor surface.
