We present a regrowth and grating free InP-based single-facet teardrop laser consisting of a 1×2 multi-mode-interferometer and a waveguide loop reflector. The fabricated laser demonstrated CW lasing ...

Reflections from a fiber positioned at a very short distance from the output facet of a DFB laser diode are shown to induce variations of both mean turn-on time and time jitter under gain switching.
