Abstract: A light source for providing light comprises a light emitting layer and a lens comprising a periodic structure therein that is periodic along at least one direction in a plane. The structure includes or is formed from at least two optically transparent materials of different optical indices. The lens is separated from the light emitting layer, and the radiation propagating from the light emitting layer within an angle to a line normal to the plane will be transmitted by the lens to a far field in an index-guided mode. The separation between the light emitting layer and the lens is such that near field radiation propagating from the light emitting layer towards the lens not within said angle to the line will be scattered and redirected by the first lens to the far field to thereby collimate the radiation propagating from the light emitting layer to the far field.

Abstract: A tunable wavelength filtering device is presented in which the tuning mechanism is based on altering the incident angle to an optical thin film coating stack, or thin film optical filter. Rotating mirrors, such as Micro-Electro-Mechanical Systems (MEMS) tilt-mirrors, are used to alter the incident angle of the optical beam coming from an input fiber, and also to aim or align the exiting beam to an output optical fiber. The optical thin film coating stack can be implemented onto a glass substrate, to form a thin film filter chip. The thin film filter chip can be fixed in place, and the incident angle and exiting angle of the optical beam is varied by adjusting the tilt angle of the two rotating mirrors.

Abstract: Light emitting diode (LED) lighting fixtures are presented that use a low-pass filter to smooth out or eliminate discrete, step changes in LED light fixture brightness, that may result from the use of digital brightness level settings. Because some lighting applications require a fast response to changes in the set brightness level, and some applications require a slower response, one set of examples use a switchable RC low-pass filter circuit, with two or more selectable RC time constant values. Another set of examples use a programmable resistance integrated circuit to achieve a more continuously-variable time constant, for greater flexibility in adjusting the response time of the LED lighting fixture, in response to user brightness inputs. The user is able to control the maximum rate of change of the LED light fixture's brightness, in response to changes in the brightness setting.

Abstract: The color uniformity of a light spot is measured by providing an image of the light spot by means of a camera or camera sensor with sensor elements, each of the sensor elements capturing a set of three or more color component values that together define a set of pixel values at such sensor element, wherein the image includes a plurality of sets of pixel values. The method also derives for each of the plurality of sets of pixel values at a corresponding sensor element a first ratio between a first pair of the pixel values or of values obtained therefrom in such set. Preferably a second ratio is also derived between a second pair of the pixel values or of values obtained therefrom in such set, where the second pair is different from the first pair. Where the sensor elements used each provides a single intensity value instead of multiple pixel values of different colors, light is projected onto a spot of the camera or camera sensor along an optical path with a different one of three or more different color filters sequentially in the path. For each sensor element a first ratio is derived between a first pair of the intensity values of different colors provided by such sensor element or of values obtained therefrom and preferably also a second ratio is derived between a second pair of the intensity values of different colors or of values obtained therefrom provided by such sensor element different from the first pair.

Abstract: Wavelength-tuning optical filters are presented that also allows for the tuning or real-time adjustment of its bandwidth, or passband width. The bandwidth-adjustable tunable optical filters use one or more diffraction gratings that are fixed in place to provide angular dispersion of different wavelengths. A first rotatable or tilting mirror is used to adjust the angle of incidence of an input optical beam to the diffraction grating or diffraction grating system, while a second rotatable or tilting mirror is used to aim the diffracted optical beam back through the diffraction grating or diffraction grating system, so that a subset of the incoming wavelengths are optically aligned to the end face of an output fiber. The first rotatable or tilting mirror provides tuning or adjustment of the bandwidth or passband width of the tunable optical filter, while the second rotatable or tilting mirror tunes or adjusts the center wavelength of the passband.
