The O-band coarse wavelength-division (de) multiplexing (CWDM) has been extensively
used in data-center optical communications, whereas it's still challenging to reduce crosstalk …

We demonstrate a cascaded Mach-Zehnder interferometer (MZI) based coarse wavelength
division multiplexing (CWDM)(de) multiplexer on silicon-on-insulator with its spectral …

Modern optical communications rely on high-resolution, high-bandwidth filtering to maximize
the data-carrying capacity of fiber-optic networks. Such filtering typically requires high …

We propose a DSP-free coherent-lite system that requires neither high-speed DSP nor high-
resolution signal converters for deployment inside datacenters over single mode fiber links …

A low-crosstalk and flat-top 4-channel coarse wavelength-division multiplexing (de)
multiplexer is proposed and demonstrated. The cascaded Mach-Zehnder interferometers …

We have proposed a three-port high efficient channel-drop filter (CDF) with a coupled cavity-
based wavelength-selective reflector, which can be used in wavelength division multiplexing …

We propose and experimentally demonstrate a low-loss and low-crosstalk Mach-Zehnder
mode/wavelength multi/demultiplexer for WDM/MDM transmission based on a Si-photonics …

The advancement of digital coherent technologies has dramatically increased the system
capacity per single-core single-mode fiber to the point that we can now approach the …

We present, to the best of our knowledge, the first known detailed analysis and fair
comparison of complexity of a 56 Gb/s multi-band carrierless amplitude and phase (CAP) …

Wavelength-division-multiplexing (WDM) networks with wide channel grids and bandwidths
are promising for low-cost, low-power optical interconnects. Wide-bandwidth, single-band …
