We successfully demonstrate a monolithic integrated dual-polarization in-phase/quadrature (IQ) modulator based on thin-film lithium niobate platform with silicon substrate, which consists of IQ modulators, spot-size converters, and polarization rotator combiner. When coupled maintaining fibers, the measured insertion loss is 12 dB. In addition, we experimentally achieve single-carrier 1.6 Tb/s net bitrate transmission.
We successfully demonstrated a real-time 800Gb/s single-carrier SHC-BiDi transmission with the proposed APC solution tracking up to record 200 krad/s SOP rotation speed without performance penalty. A ~10km EDFA is achieved via low cost DFB laser.
We successfully demonstrated a real time 6.4Tbps self-homodyne coherent transmissions without polarization tracking through specially designed 10km multi-core fibers with 1 maintaining core and 8 normal single-mode cores, using the wavelength unlocked DFB laser.
We successfully demonstrate a monolithic integrated dual-polarization (DP) IQ modulator based on thin-film lithium niobate (TFLN) platform with silicon substrate, which consists of modulators, spot-size converters (SSCs) and polarization rotator combiner (PRC). After coupled maintaining fibers, the measured insertion loss is 12 dB. In addition, we experimentally achieve single-carrier 1.6 Tb/s net bitrate transmission.
We propose and experimentally verify a self-homodyne coherent (SHC) transmission scheme based on 1+8 multicore fiber with one polarization-maintaining central core eight ordinary single-mode cores. The multi-core can take advantage of SHC by reducing the path mismatch introduced fiber, does not require an additional polarization control unit. Since it provides 8 spatial channels under 150μm cladding diameter, optical capacity density per unit area has been improved. fabrication process...

In systems, BiDi uses single silicon photonics (SiP) based polarization tracker remote homodyne and achieved record of 8 krad/s endless SOP tracking speed wavelength demultiplexing dual local...
Point-to-multi-point (P2MP) optical networks using coherent digital subcarrier multiplexing (DSCM) can offer a better match to the hub-and-spoke traffic pattern. To reduce computational complexity of signal processing at leaf nodes, hub-site chromatic dispersion (CD) pre-compensation be adopted but residual CD will affect timing recovery (TR). In this paper, we present CD-tolerant TR algorithm for 400Gb/s P2MP DSCM over 320 km transmission. The experimental results show that proposed...
