  • Patent number: 7356210
    Abstract: A variable optical attenuator multiplexer having at least one thermal isolating optical joint. The variable optical attenuator multiplexer including a plurality of planar lightwave circuit components, such as, for example a combination of an array waveguide grating, a variable optical attenuator, and/or a power monitor. The planar lightwave circuit components are joined with an optical adhesive. The components may be thermally isolated by the formation of a widened space or gap between the component joints, and/or by creating a trench in the optical adhesive.

  • Publication number: 20040264842
    Abstract: The coupling properties of an optical device having at least two inputs and two outputs may be more accurately measured by simultaneously measuring the optical transmission through all outputs for light coupled to each input to the device. An optical switch may be used to selectively couple the light to each of the device inputs. This removes the need to remove the light source from one input and to reconnect it to another input. By proper processing of the measured optical transmission corresponding to each input, an accurate and precise value for the transfer function, including polarization properties, of the device may be obtained independent of the insertion losses in the system.
