A grating-based Fabry-Perot (FP) cavity-coupled microring resonator on a silicon chip is reported to demonstrate an all-optically tunable Fano resonance. In the device, an add-drop microring resonator (MRR) is employed, and one of the two bus waveguides is replaced by an FP cavity consisting of two sidewall Bragg gratings. By choosing the parameters of the gratings, the resonant mode of the FP ...
We demonstrate the generation of error-free binary-phase-shift-keyed (BPSK) data at 5 Gb/s using a silicon microring modulator. The microring-modulated BPSK signal is propagated at fiber lengths up to 80 km, maintaining error-free performance, while demonstrating resilience to chromatic dispersion. Bit-error-rate measurements and eye diagrams show near equivalent performance of a microring-base...
We demonstrate the hybrid integration of a lithium niobate microring resonator with silicon nitride waveguide in vertical configuration to achieve efficient light coupling. The is fabricated on insulator (LNOI) substrate using photolithography assisted chemo-mechanical etching (PLACE). A fused silica cladding layer deposited LNOI ring resonator. further produced by first fabricating trench whil...
A high-speed photonic temporal differentiator based on cascaded SOI microring resonators is proposed and experimentally demonstrated in this study. The first-order all-optical differentiation functionality is realized through approaching the critical coupling condition of the cascaded microring resonators. A three-stage double channel side-coupled cascaded microring structure is used to provide...
A 640 Gbit/s NRZ OTDM signal has been successfully generated for the first time by format conversion of a 640 Gbit/s OTDM signal from RZ to NRZ. First, a coherent 640 Gbit/s OTDM RZ signal is generated by wavelength conversion of the original incoherent OTDM signal utilizing Kerr switching in a highly nonlinear fiber. Second, RZ-to-NRZ format conversion is achieved in a specially designed silic...
