100 Gb/s SDM-PON Using Polarization-Diversity Silicon Micro-Ring Resonator Enhanced DML

Coupled-ring-resonator-based silicon modulator for enhanced performance.

A compact silicon coupled-ring modulator structure is proposed. Two rings are coupled to each other, and only one of these rings is actively driven and over-coupled to a waveguide, which enables high modulation speed. The resultant notch filter profile is steeper than that of the single ring and has exhibited a smaller resonance shift and lower driving electrical power. Simulation results inclu...

Piezoelectrically tuned silicon nitride ring resonator

Typical integrated optical phase tuners alter the effective index. In this paper, we explore tuning by geometric deformation. We show that tuning efficiency, VπL, improves as the device size shrinks down to the optimal bend radius, contrary to conventional index-shift based approaches where VπL remains constant. We demonstrate that this approach is capable of ultra-low power tuning across a ful...

Silicon Micro-Ring Modulator Modeling

On-chip switching of a silicon nitride micro-ring resonator based on digital microfluidics platform.

We demonstrate the switching of a silicon nitride micro ring resonator (MRR) by using digital microfluidics (DMF). Our platform allows driving micro-droplets on-chip, providing control over the effective refractive index at the vicinity of the resonator and thus facilitating the manipulation of the transmission spectrum of the MRR. The device is fabricated using a process that is compatible wit...

Selective and reversible ammonia gas detection with nanoporous film functionalized silicon photonic micro-ring resonator.
