Photonic integration has seen tremendous progress over the previous decade, and several
integration platforms have reached industrial maturity. This evolution has prepared the …

In this paper, we compare ring resonator and three-port Mach-Zehnder Interferometer (MZI)
devices fabricated on silicon-on-insulator for the purpose of refractive index sensing. Their …

In this contribution, we present the development of a passively demodulated interferometer
based on 3× 3 waveguide couplers to measure light absorption of trace gases and aerosol …

A photonic implementation of a wavelength meter typically applies an interferometer to
measure the frequency-dependent phase shift provided by an optical delay line. This work …

Monitoring the state of the optical network is a key enabler for programmability of network
functions, protocols and efficient use of the spectrum. A particular challenge is to provide the …

Up-to-date network telemetry is the key enabler for resource optimization by a variety of
means including capacity scaling, fault recovery, network reconfiguration. Reliable optical …

Integrated photonic sensor systems are miniaturized, mass-producible devices that leverage
the mature semiconductor fabrication technology and a well-established ecosystem for …

Up-to-date network telemetry is the key enabler for resource optimization by capacity
scaling, fault recovery, and network reconfiguration among other means. Reliable optical …

We propose a structural optimization method based on a real-coded micro-genetic algorithm
to realize a weakly guided 2× 2 multimode interference (MMI) coupler with low imbalance …

We present wafer-scale measurements of the phase errors of 120° and 90° optical hybrids,
using 3× 3 and 4× 4 MMIs, respectively. The deviation of the median of the measurements …
