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…
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…
