A very strong selection mechanism is provided in a tunable vertical cavity surface emitting laser (VCSEL) by manipulating the laser threshold to be different for TE and TM polarization by a employing a subwavelength grating in the laser cavity. The laser selects the polarization with the lowest threshold. The grating does not diffract and does not add loss to the cavity. It works by creating a large birefringence layer between the semiconductor and air sub-cavities of the full VCSEL. Multilayer stack calculations show that this results in a lower threshold for the TM polarization over the TE. This subwavelength grating layer, in one embodiment, replaces the AR coating on the semiconductor surface.

Tunable VCSELs (TVCSELs) employing expanded material systems with expanded mechanical/optical design space for semiconductor DBR mirrors on GaAs substrates. One is the InGaAs / AlGaAsP material system. It adds indium In to decrease InGaAs H-layer bandgap for higher refractive index and higher DBR layer refractive index contrast. Adding phosphorus P gives independent control of bandgap and strain of AlGaAsP low refractive index L-layers. The tensile strain of AlGaAsP L-layer compensates compressive strain of InGaAs H-layer and lowers the cumulative strain of the multilayer DBR structure. Another option is the InGaAsN(Sb) / AlGaAsP material system, where both types of layers can be lattice matched to GaAs. It uses indium In and nitrogen N, and possibly antimony Sb, to get independent control of strain and bandgap, and thus refractive index, of dilute nitride InGaAsN(Sb) H-layers, with lower bandgap and higher refractive index than starting GaAs. Using expanded material system enables reliable DBR mirrors with higher reflectivity and spectral bandwidth and tunable VCSELs with wider tuning range.

A circuit for detecting electromagnetic radiation includes a pyroelectric sensor element connected to convert electromagnetic radiation into an electric signal. An n-channel junction field effect transistor is connected to receive the electric signal. A printed circuit board includes at least one low inductance low resistance area to provide a ground path for all alternating current components. A first capacitor is connected between the FET source terminal and a second capacitor is connected between the FET drain terminal and ground. A gate resistor is connected in parallel with the sensor element or a resistor is included in the sensor elements.

An infra-red motion detector lens (50) is disclosed. The lens is configured to focus radiation on a 2 x 2 quad detector (10) that has a plurality of detector regions (11-14) capable of providing a first signal or a second signal. The lens comprises a series of lenslets, each of which can image respective regions (60, 70). The fields of view of the lenslets are partially overlapping in such a way that a source of radiation in a particular location can simultaneously project radiation onto two detector regions (11-14) through more than one respective lenslet. The detector regions (11-14) are diagonally opposite one another and are arranged to provide the same type of signal. A grid of overlapping lenslets can be constructed in this way so that two lenslets can increase the signal strength created at the detector by focusing radiation onto the same detector to create the same type of signal.

F21V 23/04 - Agencement des éléments du circuit électrique dans ou sur les dispositifs d’éclairage les éléments étant des interrupteurs
A light mixing and folding lamp (200) includes an LED assembly (218) with two or more LED chips that direct light into the ingress end of a light mixing rod (236). The light mixing rod is positioned to pass through an aperture (244) in a concave second reflecting element (216), and mixed light emerges from the egress end of the light mixing rod, where it is directed toward a first reflecting element (204) positioned near a focal point of the second reflecting element. The first reflecting element reflects mixed light emerging from the egress end of the light mixing rod, folding the mixed light back toward a concave reflecting surface of the second reflecting element. The second reflecting element reflects light from the first reflecting element forward, where the light emerges from the lamp directed toward a subject to be illuminated.

A light engine for a high intensity light (10) that may be compliant with FAA or ICAO standards is disclosed. The light engine (100) includes a first light emitting module (104) having a light emitting diode mounted in a horizontal plane. A reflector (108) has a reflective surface (110) in perpendicular relation to the light emitting diode. The reflective surface is defined by combining the integrals of a required beam emission specification with the integrals of the light emitting diode (122,124). The resulting reflective curve is modified with focal length and curve based on horizontal plane position variables relative to the light emitting diode around an azimuth angle.

F21Y 101/02 - Structure miniature, p. ex. diodes électroluminescentes (LED)
A system for holding an optical rod, contains an optical mount having a hole traversing throughout a body of the optical mount, wherein the optical mount is a c-shaped collar clamp. The system also contains an optical rod having a circumferential area and a split sleeve encompassing the optical rod circumferential area for at least a portion of the axial length of the optical rod. The split sleeve and optical rod are inserted within the optical mount hole, and the split sleeve contains an inner surface and an outer surface, where material of the split sleeve does not conform intimately with the optical rod so as to maintain total internal reflection conditions.
