Paper Abstract

Requirements for directly modulated semiconductor lasers are investigated in terms of directly measurable laser and link parameters. Data rates comparable to the bandwidth imposed by the active layer design are considered, and performance is assessed in terms of laser resonance frequency and damping. Link critical variables such as contrast ratio, fall time and error rate are thereby related directly to parameters extracted from static measurements. To allow error free operation, a resonance frequency equal to the data rate is acceptable, but to ensure a fast fall time, resonance frequencies exceeding one and a half times the data rate are necessary.
