Historical development of the threshold current of semiconductor lasers. Different marker colors indicate different types of lasers and the numbers mark references, which can be found in the ...

The threshold current — the level at which the laser switches on — of the photonic-bandgap laser designed by Zhou et al. 4 is 300 μA, much more than the threshold of 40 μA and lower seen in ...
