We review work on self-homodyne detection (SHD) for optical communication systems. SHD
uses a transmitted pilot-tone (PT), originating from the transmitter laser, to exploit phase …

This paper provides an overview of latest progress on the novel advanced digital signal
processing (DSP) techniques for long-haul mode division multiplexing (MDM) systems with …

We demonstrated simultaneous usage of 228 spatial channels (effectively) within a strand of
fiber. We fabricated a 13-km 39-core 3-mode fiber and constructed a bi-directional space …

We demonstrate transmission of a comb-based 10 Tb/s 50× 20 Gbaud PM-64QAM
superchannel using frequency comb regeneration to reduce carrier offsets and allow for self …

We propose a self-homodyne system for next generation intra-datacenter networking. The
proposed system has a higher spectral efficiency for the modulated signal compared to the …

Towards 100G beyond large-capacity optical access networks, wavelength division
multiplexing (WDM) techniques incorporating with space division multiplexing (SDM) and …

We investigate a high-capacity, space-division-multiplexed (SDM) transmission system
using self-homodyne detection (SHD) in multi-core fiber (MCF). We first investigate SHD …

We demonstrate and characterize an all-optical self-homodyne (SH) frequency
superchannel enabled by comb regeneration at the receiver. In order to generate the …

The limits of narrowband Brillouin gain for improving the carrier to noise ratio (CNR) of
spectral lines is evaluated for 64-QAM communications. Calculations of the change in CNR …

We investigate self-homodyne coherent transmission employing space division multiplexing
(SDM), where a continuous wave laser source is divided to produce spatially multiplexed …
