Publication number: 20240272369Abstract: Embodiments herein describe using an actuator to tune a waveguide. In one embodiment, the tunable waveguide includes a gap between the waveguide and cladding. The actuator can compress the cladding to shrink this air, bringing the cladding closer to the waveguide. Doing so changes the effective refractive index of the waveguide. Alternatively or additionally, the actuator can increase the gap.Type: ApplicationFiled: February 14, 2023Publication date: August 15, 2024Inventors: Matthew J. TRAVERSO, Donald J. ADAMS

Patent number: 11762155Abstract: Embodiments herein describe an optical system that includes a photonic integrated circuit (PIC) bonded to a package containing an electrical integrated circuit (EIC). However, this bond can prevent an edge coupler from optically aligning an optical fiber to an edge of the PIC in order to transfer optical signals. To provide room for the edge coupler, the PIC is arranged to overhang the package containing the EIC so that the package does not interfere with the ability of the edge coupler to align with the side or edge of the PIC. In this manner, an optical fiber can be optically aligned (e.g., butt coupled) to the edge of the PIC rather than having to use a grating coupler or some other less efficient optical coupling in order to transfer optical signals between the PIC and the optical fiber.Type: GrantFiled: August 25, 2021Date of Patent: September 19, 2023Assignee: Cisco Technology, Inc.Inventors: Vipulkumar K. Patel, Matthew J. Traverso, Sandeep Razdan, Aparna R. Prasad
