Simultaneous multi-wavelength mode-locked DFB laser based on waveguide Bragg grating microcavities

{{output}}
We demonstrate, for the first time to the best of our knowledge, a monolithic multi-wavelength mode-locked distributed feedback (DFB) laser based on waveguide Bragg grating microcavities, achieving simultaneous three-wavelength lasing near 1.55 μm within a si... ...
