Strong polarization mode coupling in microresonators
Sven Ramelow, Alessandro Farsi, Stéphane Clemmen +6
We observe strong modal coupling between the TE00 and TM00 modes in Si3N4 ring resonators revealed by avoided crossings of the corresponding resonances. Such couplings result in si…
Microresonator-Based Comb Generation without an External Laser Source
Adrea R. Johnson, Yoshitomo Okawachi, Michael R. E. Lamont +3
Recent developments demonstrate that parametric four-wave mixing (FWM) in high-Q microresonators is a highly promising and effective approach for optical frequency comb generation,…
Modelocking and Femtosecond Pulse Generation in Chip-Based Frequency Combs
Kasturi Saha, Yoshitomo Okawachi, Bonggu Shim +7
Development of ultrashort pulse sources has had an immense impact on condensed-matter physics, biomedical imaging, high-field physics, frequency metrology, telecommunications, nonl…
Octave-spanning frequency comb generation in a silicon nitride chip
Yoshitomo Okawachi, Kasturi Saha, Jacob S. Levy +3
We demonstrate a frequency comb spanning an octave via the parametric process of cascaded four-wave mixing in a monolithic, high-Q silicon nitride microring resonator. The comb is…
High-Performance Silicon-Based Multiple Wavelength Source
Jacob S. Levy, Kasturi Saha, Yoshitomo Okawachi +3
We demonstrate a stable CMOS-compatible on-chip multiple-wavelength source by filtering and modulating individual lines from a frequency comb generated by a microring resonator opt…
A Silicon-Based Monolithic Optical Frequency Comb Source
Mark A. Foster, Jacob S. Levy, Onur Kuzucu +3
Recently developed techniques for generating precisely equidistant optical frequencies over broad wavelength ranges are revolutionizing precision physical measurement [1-3]. These…
