摘要： Optical integrated circuits are disclosed having a gap traversing the lens or the waveguide grating and an actuator that controllably positions the optical integrated circuit on each side of the gap. As a result, the thermal sensitivity of the optical integrated circuits, for example, arrayed waveguide gratings, is mitigated. Also disclosed are methods for fabricating optical integrated circuits employing the gap and actuator.

摘要： Systems and methods for an isothermal thin film heater are provided. The isothermal thin film heater mitigates temperature variations in an optical circuit, such as an arrayed-waveguide grating. The thin film heater comprises a conductive plate and at least one heating element trace coupled to the conductive plate for heating the optical circuit. The heating element trace(s) is arranged around a periphery portion of the conductive plate such that concentric arcs are formed by the heating element trace(s). A sensor for sensing the temperature of the thin film heater and/or the optical circuit can also be provided.

摘要： A planar lightwave circuit assembly has an optical layer on a substrate. The substrate is attached to one face of a riser. A layer of a material having properties substantially the same as the substrate is attached to the other face of the riser. The layer of material counteracts the tendency of the assembly to bow as a result of differences in the coefficients of thermal expansion of the riser and substrate. This reduces stress-induced changes in performance characteristics of lightwave circuits in the optical layer.
