Dispersion-supported direct-detection mode group division multiplexing using commercial multimode fiber couplers.
In this Letter, an intensity-modulation direct-detection mode group multiplexing system is investigated. The system does not use highly modally selective optics: multiplexing and demultiplexing is done in commercial multimode couplers and modal diver

WDM-compatible mode-division multiplexing on a silicon chip.
Significant effort in optical-fibre research has been put in recent years into realizing mode-division multiplexing (MDM) in conjunction with wavelength-division multiplexing (WDM) to enable further scaling of the communication bandwidth per fibre. I

Magnetically controllable wavelength-division-multiplexing fiber coupler.
In this paper, a magnetically controllable wavelength-division-multiplexing (WDM) fiber coupler has been proposed and experimentally demonstrated. A theoretical model has been established to analyze the influences of the weak as well as strong coupli

Time domain multiplexed spatial division multiplexing receiver.
A novel time domain multiplexed (TDM) spatial division multiplexing (SDM) receiver which allows for the reception of >1 dual polarization mode with a single coherent receiver, and corresponding 4-port oscilloscope, is experimentally demonstrated. Rec

Compact spatial multiplexers for mode division multiplexing.
Spatial multiplexer (SMUX) for mode division multiplexing (MDM) has evolved from mode-selective excitation, multiple-spot and photonic-lantern based solutions in order to minimize both mode-dependent loss (MDL) and coupler insertion loss (CIL). This

Molecular-absorption-induced thermal bistability in PECVD silicon nitride microring resonators.
The wavelength selective linear absorption in communication C-band is investigated in CMOS-processed PECVD silicon nitride rings. In the overcoupled region, the linear absorption loss lowers the on-resonance transmission of a ring resonator and incre

Thermal tuning of Kerr frequency combs in silicon nitride microring resonators.
Microresonator based Kerr frequency comb generation has many attractive features, including ultrabroad spectra, chip-level integration, and low power consumption. Achieving precise tuning control over the comb frequencies will be important for a numb

Broadband and fabrication-tolerant on-chip scalable mode-division multiplexing based on mode-evolution counter-tapered couplers.
A broadband and fabrication-tolerant on-chip scalable mode-division multiplexing (MDM) scheme based on mode-evolution counter-tapered couplers is designed and experimentally demonstrated on a silicon-on-insulator (SOI) platform. Due to the broadband

Densely packed waveguide array (DPWA) on a silicon chip for mode division multiplexing.
A densely packed waveguide array (DPWA) structure for mode division multiplexing on a silicon chip is proposed. The DPWA consists of several narrow waveguides with different widths, which are densely packed with gaps of 100nm. The lateral dimension o

Towards 100 channel dense wavelength division multiplexing with 100GHz spacing on silicon.
A 1 by 4 wavelength division multiplexer with 0.5nm bandwidth and no free spectral range limitation is demonstrated on silicon. The device utilizes wide bandwidth filters cascaded with ring resonators in order to select specific ring resonator modes
