Rf beam steering using on-ohip optical true time delay on 3 micrometer siliocn on insulator platfrom
Somnath Paul, Jussi Saily, Markus Schroder +2
We present the design, packaging, and system-level experimental demonstration of a reconfigurable 5-bit, 4-channel optical true time delay (OTTD) chip realized on a 3 micrometer th…
InP optical amplifiers with Euler U-bend waveguide geometry for low-loss flip-chip hybrid integration
Heidi Tuorila, Jukka Viheriälä, Lee Jae-Wung +4
We report on the development of InP-based semiconductor amplifiers with a U-bend waveguide geometry having the input and output ports on one facet only. This waveguide geometry sim…
Second order add/drop filter with a single ring resonator
Matteo Cherchi, Fei Sun, Markku Kapulainen +3
We show theoretically and experimentally how a flat-top second-order response can be achieved with a self-coupled single add-drop ring resonator based on two couplers with differen…
Tapered MMI splitters with unconstrained splitting ratio on a thick SOI platform
Matteo Cherchi, Mikko Harjanne, Katherine Bryant +3
We have systematically studied multimode interferometer (MMI) splitters made from multiple tapered sections. The goal is to create a library of robust and low-loss splitters coveri…
Flat-top interleavers based on single MMIs
Matteo Cherchi, Fei Sun, Markku Kapulainen +2
We demonstrate for the first time flat-top interleavers based on cascaded Mach-Zehnder interferometers (MZIs) which use only single multimode interferometers (MMIs) as power splitt…
Low-error and broadband microwave frequency measurement in a silicon chip
Mattia Pagani, Blair Morrison, Yanbing Zhang +6
Instantaneous frequency measurement (IFM) of microwave signals is a fundamental functionality for applications ranging from electronic warfare to biomedical technology. Photonic te…
New silicon photonics integration platform enabled by novel micron-scale bends
Matteo Cherchi, Sami Ylinen, Mikko Harjanne +2
Even though submicron silicon waveguides have been proposed for dense integration of photonic devices, to date the lightwave circuits on the market mainly rely on waveguides with m…
