A thin film of electron-trapping material (ETM), when combined with suitable optical bistability, is considered as medium for optical implementation of bio-inspired neural nets. The optical mechanism of ETM under blue light and NIR exposure has the inherent ability at the material level to mimic the crucial components of the stylized Hodgkin-Huxley model of biological neuron. Combining this uni...

Broadband homodyne detection of the light transmitted by a Fabry-Perot cavity containing a strongly-coupled (133)Cs atom is used to probe the dynamic optical response in a regime where semiclassical theory predicts bistability but strong quantum corrections should apply. While quantum fluctuations destabilize true equilibrium bistability, our observations confirm the existence of metastable sta...

We demonstrated a 1×4 all-optical packet switch using injection-locking in a FabryPerot laser diode for all-optical header processing and cross gain modulation in an SOA for packet switching. 2004 Optical Society of America OCIS codes: (230.1150) All-optical devices; (190.1450) Bistability; (140.3520) Lasers, injection-locked

We have demonstrated, the first time to our knowledge, a low input intensity (16nW/μm) high contrast (10:1) optical AND gate based on a VCSOA. In the experiment the device also shows an optical gain of 10dB. © 2003 Optical Society of America OCIS codes: (190.1450) Bistability; (200.4660) Optical logic
