Transformer-based Nonlinear Equalization for DP-16QAM Coherent Optical Communication Systems
Naveenta Gautam, Sai Vikranth Pendem, Brejesh Lall +1
Compensating for nonlinear effects using digital signal processing (DSP) is complex and computationally expensive in long-haul optical communication systems due to intractable inte…
Brillouin-based phase shifter in a silicon waveguide
Luke Mckay, Moritz Merklein, Alvaro Casas Bedoya +8
Integrated silicon microwave photonics offers great potential in microwave phase shifter elements, and promises compact and scalable multi-element chips that are free from electrom…
Chip-based Brillouin processing for carrier recovery in coherent optical communications
Elias Giacoumidis, Amol Choudhary, Eric Magi +8
Modern fiber-optic coherent communications employ advanced spectrally-efficient modulation formats that require sophisticated narrow linewidth local oscillators (LOs) and complex d…
Lossless integrated RF photonic filter with record-low noise figure and 116 dB of dynamic range
Yang Liu, Jason Hotten, Amol Choudhary +2
We report a silicon nitride RF photonic notch filter with unprecedented performance including 8 dB of RF gain, record-low noise figure of 15.6 dB, and spurious-free dynamic range o…
