Microresonator-based solitons for massively parallel coherent optical communications

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Victor Brasch, Arne Kordts, Maxim Karpov, Miles Henry Anderson

Solitons are waveforms that preserve their shape while propagating, as a result of a balance of dispersion and nonlinearity(1,2). Soliton-based data transmission schemes were investigated in the 1980s and showed promise as a way of overcoming the limitatio ...

Higher Order Mode Suppression in high-Q Anomalous Dispersion SiN Microresonators for Temporal Dissipative Kerr Soliton Formation

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Victor Brasch, Arne Kordts, Hairun Guo

Frequency comb generation based on dissipative Kerr solitons (DKS) in microresonators is important for many applications. We show higher order mode suppression in silicon nitride microresonators, that reduces avoided modal crossing to enable DKS generation ...
