A Degenerate-Mode-Selective Coupler for Stable DSP-free MDM Transmission

Weakly-coupled mode division multiplexing (MDM) has been intensively investigated in recent years. In order to be compatible with conventional intensity modulation and direct detection systems, eff…

Tilting of Bragg Waveguide Gratings Using Two-Dimensional Sampling Structures

Experimental Demonstration of Single Sideband Modulation Utilizing Monolithic…

Single sideband (SSB) modulation based on a monolithic integrated optically injection-locked (MOIL) DFB laser is demonstrated experimentally. To our knowledge, this is the first time to realize SSB…

Tunable, Single-Wavelength Fiber Ring Lasers Based on Rare Earth-Doped, Doubl…

Single-wavelength fiber ring lasers are demonstrated using rare earth-doped, double-peanut fiber interferometers (RDDPFIs) as the tunable narrow-band filters. With the relatively stronger opto-ther…

GIMF-Based SA for Generation of High Pulse Energy Ultrafast Solitons in a Mod…

A mode-locked high pulse energy fiber laser with a linear cavity by using an all-fiber structured graded index multimode fiber (GIMF) based saturable absorber (SA) is presented. The saturable absor…
