摘要： A laser system includes a laser diode that, upon activation, selectively produces a continuous wave of laser light or uniformly spaced, intermittent pulses of laser light. The system further includes a laser focuser with a plurality of lenses that focus the laser light produces by the laser diode and direct the laser light to an optical resonator. The optical resonator includes a lasing medium that, when intersected by the laser light from the laser diode, produces a beam of laser light with a wavelength that may be used for therapeutic treatment. The system is operable to produce the therapeutic laser light when the laser diode is operating in either the continuous wave mode or the pulsed mode, without moving components of the system relative to one another.

摘要： There is described a dispersive optical device (10) comprising an optically dispersive element (P) with a pair of angled surfaces (pA, pB), namely an upper surface (pA) and a lower surface (pB), positioned along the path of incident light (L) to cause refraction and dispersion of the incident light (L) entering the upper surface (pA) and exiting the lower surface (pB). The dispersive optical device (10) further comprises a mirror element (M) positioned under the lower surface (pB) and angled with respect to the lower surface (pB) to cause dispersed light emerging from the lower surface (pB) to be reflected back towards and through the optically dispersive element (P) to cause further refraction and dispersion of the dispersed light entering the lower surface (pB) and exiting the upper surface (pA). Such dispersive optical device (10) may in particular be used as optical concentrating device for solar energy harvesting.

摘要： Systems and methods which provide a high-throughput point source light coupling structure (120) implementing a condenser (122) configured according to one or more condenser (122) configuration rules are described. Embodiments of a high-throughput point source light coupling structure (120) utilize a birefringent plate (341, 342) configuration in combination with a condenser (122) and point source (121) to provide a light coupler structure (120) for a birefringent-static-Fourier transform interferometer implementation. According to some examples, the optical axis of a first and second birefringent plate (341, 342) of a birefringent plate (341, 342) configuration are not in the same plane. The condenser (122) of the high-throughput point source light coupling structure (120) of embodiments is provided in a defined (e.g., spaced, relational, etc.) relationship with respect to the point source (121) and/or a camera lens (131) used in capturing an interference pattern generated by the light coupling structure (120). The high-throughput point source light coupling structure (120) herein may be provided as external accessories for processor-based mobile devices (130) having image capturing capabilities.

摘要： La presente invención se refiere a un dispositivo óptico que permite controlar la proyección de la luz de manera que ésta sale paralela a un dispositivo de apantallamiento multicelda no activo, con lo que dicho dispositivo de apantallamiento no es iluminado por el haz de luz, percibiendo el usuario la luz con toda su intensidad, sin perdidas de intensidad debido a la reflexión de dicho dispositivo de apantallamiento, donde además, debido a su bajo perfil, el dispositivo óptico permite su integración en una luminaria con una cota de altura reducida, que es también objeto de la presente invención.

摘要： To extract light from a light-emitting diode (and thereby improve efficiency of the display), a microlens stack may be formed over the light-emitting diode. The microlens stack may include an array of microlenses that is covered by an additional single microlens. Having stacked microlenses in this way increases lens power without increasing the thickness of the display. The array of microlenses may be formed from an inorganic material whereas the additional single microlens may be formed from an organic material. The additional single microlens may conform to the upper surfaces of the array of microlenses. An additional low-index layer may be interposed between the light-emitting diode and the array of microlenses. A diffusive layer may be formed around the light-emitting diode to capture light emitted from the light-emitting diode sidewalls.

摘要： Various embodiments provide a method for fabricating a couplable electro-optical device. In an example embodiment, the method includes fabricating at least one raw electro- optical device on a substrate; applying lens material to a working stamp; aligning the substrate and the working stamp; pressing the substrate onto the lens material until the distance between the substrate and the working stamp is a predetermined distance; and curing the lens material to form an integrated lens secured to the at least one electro-optical device on the substrate. An anti-reflective coating layer may be optionally applied on top of the molded lens. The couplable electro-optical device may be incorporated into a receiver, transmitter, and/or transceiver using passive alignment to align the couplable electro-optical device to an optical fiber.
