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： The invention relates to a planar lightwave circuit including a two stage optical filter for use in a bi-directional transceiver. A first stage includes a non-dispersive optical filter, which enables light within in a certain wavelength range, e.g. a signal channel from a laser source, to be launched onto an input/output waveguide, while light within another wavelength range, e.g. one or more detector channels, will be directed from the input/output waveguide to a second stage. The second stage includes a reflective diffraction grating with a higher resolution than the first stage providing passbands 2 to 5 times thinner than the first stage.

摘要： The invention relates to a double-grating subtractive-dispersion optical channel multiplexer/demultiplexer for combining or separating optical channels and providing the output channels with a flat-top response. The FSR of the first grating is substantially equal to the channel spacing of the optical channels, such that the emission from the first grating achieves a cyclic offset of incidence angle into the second grating of the system.

摘要： An etched grating based chip provides a portion of each of a plurality of input optical signals from a plurality of laser diodes as optical feedback to the plurality of laser diodes, and couples the remaining light from the laser diodes onto an optical fiber, all the while maintaining a small form-factor, and meeting strict conditions regarding laser beat frequency. The present invention is applicable for both a single laser diode at a single wavelength and for an array of diodes at multiple wavelengths, which are multiplexed together in accordance with the present invention. The economics of laser diodes is much improved by decoupling the wavelength locking segment from the gain segment of the diode. Furthermore, the additional wavelength stability of such a locked diode will improve the performance and the economics of the network.
