Coherent detection offers high spectral efficiency and receiver sensitivity, but digital signal
processing (DSP)-based coherent receivers may be prohibitively power hungry for data …

This paper charts the development of spectrally efficient forms of optical orthogonal
frequency division multiplexing (OFDM) that are suited for intensity-modulated direct …

As link bit rates within and between data centers continue to increase, it is challenging to
maintain low power consumption while accommodating ever-tighter optical link budgets …

Increased traffic demands within and between data centers now necessitate low-cost and
low-power systems with per-wavelength bit rates beyond what can be easily achieved using …

Light-fidelity (LiFi) is a wireless communication technology that employs both infrared and
visible light spectra to support multiuser access and user mobility. Considering the small …

Asymmetrically clipped optical orthogonal frequency-division multiplexing (ACO-OFDM) is a
technique that sacrifices spectral efficiency in order to transmit an orthogonally frequency …

Monolithic integration of high-speed, high-efficiency photodiodes with receiver electronics
on a single silicon chip is a key to reduce cost and improve the performance of data centers' …

Intra-data-center links are scaling to 100 Gb/s per wavelength using four-level pulse-
amplitude modulation (4-PAM) and direct detection, but a restrictive link budget makes it …

We evaluate single-carrier modulation techniques for 100 Gb/s single-laser data center
interconnects. We present numerical performance analysis for various single-carrier …

Optical-orthogonal frequency division multiplexing (O-OFDM) is an effective scheme for
visible light communications (VLC), offering a candid extension to multiple access (MA) …
