Publication number: 20220320832Abstract: The present disclosure is directed to light-distribution systems on photonic integrated circuits (PIC) that split and amplify a light signal received from at least one remotely located laser into a plurality of amplified light signals, where amplification is provided by an integrated semiconductor optical amplifier (SOA). By locating the laser remotely with respect to the SOA-based PIC, the laser and PIC can be subjected to different ambient environmental conditions. Additionally, a lower-power laser can be used since the optical loss associated with splitting is compensated for by the amplification. As a result, lower current densities and optical powers can be used in both the source laser and the SOA. In some embodiments, the sequence of power splitting and amplification is repeated multiple times, thereby enabling system to scale gracefully.Type: ApplicationFiled: March 30, 2022Publication date: October 6, 2022Inventors: Brian KOCH, Alan LIU, Daniel Knight SPARACIN

Patent number: 10151939Abstract: 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.Type: GrantFiled: March 15, 2018Date of Patent: December 11, 2018Assignee: Aurrion, Inc.Inventors: Jonathan Edgar Roth, Daniel Knight Sparacin, Gregory Alan Fish
