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.
