Abstract: A waveguide heater is configured to heat an optical waveguide. The heater includes multiple heating elements and has one or two conditions selected from a group consisting of a first condition and the second condition. The first condition is the heater including multiple interior connectors that are each included in an interior electrical pathway between a pair of the heating elements where the interior connectors are connected in parallel and provide electrical communication between the heating elements included in the pair. The second condition is multiple exterior connectors that are each included in an exterior electrical pathway between electronics and a first one of the heating elements where the exterior connectors are connected in parallel and provide electrical communication between the electronics and the first heating element. The electronics are configured to apply an electrical bias to the heater. In some instances, the heater in included in a wavelength tuner.

Abstract: An on-chip optical switch based on an echelle grating and a phase tuning element is described herein. The phase tuning element may change a refractive index of the material through which an optical signal propagates, thereby causing a change in the angle of propagation of the optical signal. By dynamically tuning the phase change element, the refractive index change may be controlled such that the deviation of the optical signal causes the optical signal to be focused on a particular coupling waveguide out of an array of coupling waveguides. The echelle grating with the active phase change element form a configurable optical switch capable of switching an optical signal between two or more coupling waveguides, that may be respectively connected to different optical signal processing pathways.

Abstract: In order to bond an opto-electronic device with fiber pigtails to a larger PCB, the fibers need to be secured in place so that they don't become entangled in the bonding elements resulting in misalignment of the electronic connectors and of the optics. Accordingly, there is a need for packaged parts, which enables customers to use their own surface mount technology (SMT) bonding process without the fiber pigtails interfering with the process. Ideally, the fiber holder device is disposable and provides a spool and a fiber track to guide the fibers from the package to the spool. Ideally, an opening is provided through the spool to enable the components on the opto-electronic device to be accessed.

Abstract: The system includes an optical device having both optical components and one or more waveguides on a base. The system also includes a heat sink and a zone definer contacting the base and the heat sink. The zone definer is configured to conduct thermal energy from the optical device to the heat sink. The zone definer includes a thermal insulator having a lower thermal conductivity than both the heat sink and the base. The zone definer also includes a thermal via that extends through the thermal insulator. A via medium is positioned in the thermal via and has a higher thermal conductivity than the thermal insulator. The via medium is located under one of the optical components.
