摘要:

Differential optical switching operation with an optical input of as low as 400 fJ (0.07 fJ/&mgr;m2) was realized by using parallel‐connected AlGaAs/GaAspnpnoptical switches. An improvement in the sensitivity of more than two orders of magnitude has been attained by introduction of a new operating concept. The electrical transient time was 10 ns, almost independent of optical input levels.
