    摘要: Diffraction gratings are formed from grooves each having a reflective facet and a non-reflective facet. The net reflection of TE (Transverse Electric) and TM (Transverse Magnetic) polarizations from the grating structure is traded off against the polarization dependent reflection, by controlling the degree of metallization of the reflective facet and by ensuring that there is no metallization of non-reflective sidewalls. other diffraction gratings are manufactured from trenches etched perpendicular to a waveguide. The trenches are metallized and back-filled with a filling material having a refractive index matched to that of the waveguide. The gratings essentially have no non-reflecting sidewalls with insignificant polarization influence from side walls.

    摘要: Planar waveguide based grating devices and spectrometers, for species-specific wavelength detection for example, are disclosed. A planar waveguide spectrometer apparatus may have a microfluidic channel or compartment microfabricated integrally with a planar waveguide or hybrid assembled with the planar waveguide and optically coupled thereto. The planar waveguide may also include a thin planar substrate which is made of a transparent waveguiding optical material and has a planar multilayer, one or more input waveguides, a waveguide-based spectrometer, and one or more output waveguides integrally formed thereon. An apparatus which incorporates a planar waveguide, a diffractive construct for diffracting light through the planar waveguide onto a curved image surface, and a plurality of output waveguides emanating from the curved image surface at locations selected to extract predetermined wavelengths or wavelength ranges, is also disclosed.

    摘要: Wavelength division multiplexing (WDM) has enabled telecommunication service providers to fully exploit the transmission capacity of optical fibers. State of the art systems in long-haul networks now have aggregated capacities of terabits per second. Moreover, by providing multiple independent multi-gigabit channels, WDM technologies offer service providers with a straight forward way to build networks and expand networks to support multiple clients with different requirements. In order to reduce costs, enhance network flexibility, reduce spares, and provide re-configurability many service providers have migrated away from fixed wavelength transmitters, receivers, and transceivers, to wavelength tunable transmitters, receivers, and transceivers as well as wavelength dependent add-drop multiplexer, space switches etc. However, to meet the competing demands for improved performance, increased integration, reduced footprint, reduced power consumption, increased flexibility, re-configurability, and lower cost it is desirable to exploit/adopt monolithic optical circuit technologies, hybrid optoelectronic integration, and microelectromechanical systems (MEMS).
