Abstract

Laser switching transients in the form of turnon and turnoff delays and finite rise and fall times limit the speed of high-bit-rate digital optical systems. The turnon delay can be reduced by adding a bias to the drive current so that the off-level is above threshold,1 with the constraint that the on-off ratio of the optical signal must be sufficiently large (~10) not to degrade system performance. Even if the off-level is above threshold, the turnon and turnoff delays are nonzero, and the rise and fall times are finite.
