摘要:
The invention provides an article of manufacture, and methods of designing and making the article. The article permits or prohibits waves of energy, especially photonic/electromagnetic energy, to propagate through it, depending on the energy band gaps built into it. The structure of the article may be reduced to a pattern of points having a hyperuniform distribution. The point-pattern may exhibit a crystalline symmetry, a quasicrystalline symmetry or may be aperiodic. In some embodiments, the point pattern exhibits no long-range order. Preferably, the point-pattern is isotropic. In all embodiments, the article has a complete, TE- and TM-optimized band-gap. The extraordinary transmission phenomena found in the disordered hyperuniform photonic structures of the invention find use in optical micro-circuitry (all-optical, electronic or thermal switching of the transmission), near- field optical probing, thermophotovoltaics, and energy-efficient incandescent sources.
摘要:
A light guide (102) for bending guided light from a first direction (12) into a second direction (13) using a set of curved slits (9, 10, 11) formed in the light guiding core. The set of curved slits delimits separate bent light guide channels (14, 15, 16, 17) which guide the light through the bent light guide channels by total internal reflection.
摘要:
Various embodiments include means of reducing wavelength dependency of an optical device by causing oscillating modes within at least one terminal associated with the device.
摘要:
An optical splitter device and method are provided. The device can include a waveguide (102) having walls (104) forming a large hollow core. The waveguide can be configured to direct an optical signal through the large hollow core. An optical tap (108) can be formed through at least one wall (104) of the waveguide (102). In addition, a prism (112) can be located in the large hollow core of the waveguide and aligned with the optical tap (108). A splitter coating (110) can be provided on the prism to direct a portion of the optical signal outside of the waveguide (102) through the optical tap (108).
摘要:
A method for installing an optical tap into an optical waveguide formed in a printed circuit board which comprises obtaining a printed circuit board having an optical waveguide formed therein, cutting a transverse groove that has a front plane and a back plane into the optical waveguide, such that the back plane of the groove forms an oblique angle relative to the incident beam of light, and inserting a pre-fabricated beamsplitter into the groove so that the beamsplitter is positioned at the oblique angle of incidence relative to the beam of light to enable a predetermined portion of the beam of light to be directed out of the waveguide.
