Abstract: Embodiments of the invention describe systems, apparatuses and methods for providing athermicity and a tunable spectral response for optical filters. Finite impulse response (FIR) filters are commonly implemented in photonic integrated circuits (PICs) to make devices such as wavelength division multiplexing (WDM) devices, asymmetric Mach-Zehnder interferometers (AMZIs) and array waveguide gratings (AWGs). Athermicity of an FIR filter describes maintaining a consistent frequency transmission spectrum as the ambient temperature changes. A tunable spectral response for an FIR filter describes changing the spectrum of an FIR filter based on its application, as well as potentially correcting for fabrication deviations from the design. In addition, embodiments of the invention reduce energy dissipation requirements and control complexity compared to prior art solutions.

Abstract: Embodiments of the invention describe apparatuses, systems, and methods of thermal management for photonic integrated circuits (PICs). Embodiments include a first device and a second device comprising including waveguides, wherein the first and second devices have different thermal operating conditions. A first region is adjacent to a waveguide of the first device, wherein its optical mode is to be substantially confined by the first region, and wherein the first region has a first thermal conductivity to dissipate heat based on the thermal operating condition of the first device. A second region is adjacent to a waveguide of the second device, wherein its optical mode is to be substantially confined by the second region, and wherein the second region has a second thermal conductivity to dissipate heat based on the thermal operating condition of the second device. In some embodiments, thermal cross talk is reduced without significantly affecting optical performance.

Abstract: Embodiments describe bi-directional AWGs comprising a first input waveguide coupled to a first free propagation region to input light into a dispersive waveguide array, a second input waveguide coupled to a second free propagation region to input light into the dispersive waveguide array, a first plurality of output waveguides coupled to the first free propagation region to output light from the dispersive waveguide array received from the second input waveguide, and a second plurality of output waveguides coupled to the second free propagation region to output light from the dispersive waveguide array received from the first input waveguide. At least one of these FPRs reduces potential crosstalk received at their respective output waveguides by having at least one of their input waveguides or plurality of output waveguides angled offset from a center of the dispersive waveguide array to attenuate carrier waves that can be present at the output waveguides.
