Coherent transfer of energy (CTE) gives rise to a new peak and dip in the probe gain spectrum that move proportionally with the intracavity injected power showing that stimulated emission and absorption significantly speed up the semiconductor response. Gain modification is seen in two nondegenerate, cross-polarized modes of a microcavity laser when light is injected into only one mode, giving strong evidence for the CTE origin of the gain asymmetry.

An architectural approach that decreases the pair on-off time to much less than the individual device recovery time is presented. Two GaAs Fabry–Perot étalons, each having a 30 ns recovery time, were connected in series, defining a logic function with a fast turn-on time and a fast turn-off time. Either of two data pulses, spaced 40 ps apart, was extracted by appropriately delaying a pair of switching pulses spaced 40 ps apart. This approach has application to data generation, multiplexing and demultiplexing, self-routing, and bit permutation.
