The switching energy and speed of a bistable GaAs etalon have been measured. At liquid nitrogen temperature, the switch-on was achieved by injecting a high density of carriers with an above-band-edge 600-nm external pulse. A minimum energy of 1 nJ was required. The measured switching time was 200 ps, limited by the detector response time. The switch-off was obtained by heating the device with a 300-nJ external pulse and consequently shifting the Fabry-Perot peak. Switch-off time was about 40 ns. Room-temperature bistability was first achieved in a GaAs-AlGaAs superlattice etalon. Switch-on by a near-band-edge 845-nm pulse of 10-pJ energy was observed.Type
