    Abstract: A light-emitting diode (LED) lamp and a polygonal heat-dissipation structure thereof are provided. The LED lamp includes a polygonal heat-dissipation unit and a lighting module. The polygonal heat-dissipation unit has a polygonal hollow column and fins. The fins and the lighting module are thermally disposed on an inner surface and an outer surface of the polygonal hollow column, respectively. Thus, heat generated by the lighting module is dissipated by the fins rapidly. As the fins are thermally disposed on the inner surface of the polygon hollow column instead of being exposed, the volume of the LED lamp can be minimized, and the look of the LED lamp also can be prettified.

    Abstract: An optical device for demultiplexing an optical signal comprises a grating that receives an optical signal comprising a plurality of wavelength channels, and generates a plurality of spatially separated light beams. Each light beam is associated with a particular wavelength channel. The optical device further comprises an optical element that at least partially compensates a temperature based frequency shift associated with the spatially separated light beams. The optical device further comprises a plurality of lenses and a plurality of fibers. The plurality of lenses are arranged such that a spacing between at least a pair of lenses is determined to at least partially compensate a non-linearity introduced by the grating. Each fiber is associated with a corresponding lens and receives a corresponding light beam. At least one fiber is placed a distance that is less than a focal length associated with its corresponding lens.

    Abstract: A wavelength division multiplexing/demultiplexing device is presented utilizing a polarization-based filter to separate odd and even wavelengths, or upper and lower channels of an input optical signal. The wavelength filter first converts the input signal to a predetermined polarization. A series of birefringent waveplates provide a polarization-dependent optical transmission function such that the polarized beam is decomposed into a first beam component carrying the first spectral band at a first polarization and a second beam component carrying the second spectral band at a second, orthogonal polarization. A beam displacer spatially separates the beam components into a pair of orthogonally-polarized beams. A quarter-wave plate converts these orthogonally-polarized beams into a pair of circularly-polarized beams, which are reflected by a mirror back along parallel optical paths through the quarter-wave plate, beam displacer, and waveplates. In the return pass, the quarter-wave plate converts the reflected circularly-polarized beams into two orthogonally-polarized beams having polarizations that are rotated by 90 degrees from those in the forward pass. The waveplates further purify the spectral characteristics of the reflected beams and maintain the polarization of one of the reflected beams, while rotating the polarization of the other reflected beam by 90 degrees so that both reflected beams have substantially the same polarization. A routing element directs one of the reflected beams exiting the waveplates to a first output port and the other reflected beam to a second output port.
