Terabit-scale wavelength-multiplexed transmitter enabled by thin-film lithium tantalate

Shivaprasad U. Hulyal, Dengyang Fang, Jiachen Cai +5

Artificial-intelligence systems face a growing data-movement bottleneck and require higher interconnect bandwidth without a proportional increase in electrical power consumption or…

Optical Arbitrary Waveform Generation (OAWG) Using Actively Phase-Stabilized Spectral Stitching

Daniel Drayss, Dengyang Fang, Alban Sherifaj +10

The conventional way of generating optical waveforms relies on the in-phase and quadrature (IQ) modulation of a continuous wave (CW) laser tone. In this case, the bandwidth of the…

First Single-Carrier Transmission at Net Data Rates of 1.6 Tb/s over 9075 km and 2.4 Tb/s over 1210 km Using 300 GBd Dual-Polarization Signals and Probabilistic Constellation Shaping

Haik Mardoyan, Daniel Drayss, Sylvain Almonacil +7

We report long-haul transmissions of single-carrier 300 GBd dual-polarization signals with optical arbitrary waveform generation and measurement. We demonstrate net 1.6 Tb/s over 9…

Slice-Less Optical Arbitrary Waveform Measurement (OAWM) in a Bandwidth of More than 600 GHz Using Soliton Microcombs

Daniel Drayss, Dengyang Fang, Christoph Füllner +10

We propose and demonstrate a novel scheme for optical arbitrary waveform measurement (OAWM) that exploits chip-scale Kerr soliton combs as highly scalable multiwavelength local osc…

Mode-locked laser timing jitter limitation in optically enabled, spectrally sliced ADCs

Andrea Zazzi, Juliana Müller, Sergiy Gudyriev +5

Novel analog-to-digital converter (ADC) architectures are motivated by the demand for rising sampling rates and effective number of bits (ENOB). The main limitation on ENOB in pure…
