Abstract: In this paper the orthogonal polarization states of light are associate with “0” and “1” logical states, achieving new configurations of logical gates in different technologies: logical gates with optical nonlinearity, logical gates with directional couplers, logical gates based on interference and birefringence phenomena and logical gates with OPAL devices. Bionic concepts were implemented in these gates achieving the universal logical gates. The universal logical gates can change its internal structure in according with the functions which have to be achieved. With these universal logical gates can be achieve reconfigurable computers. These computers can modify its internal structure in according with the problems that have to be solved. Bionic concepts were implemented into reconfigurable hardware achieving in CMOS technology: the reconfigurable operational amplifier – comparator block was designed. This block can be configure in six specific configurations: two operational amplifiers, two differential comparators, one operational amplifier with NMOS input stage and one differential comparator with PMOS input stage, one operational amplifier with PMOS input stage and one differential comparator with NMOS input stage, one rail-to-rail operational amplifier, one rail-to-rail differential comparator. Also in this paper were presented the applications: optoelectronic intensity-number neural network, optoelectronic intensity-position neural network, optoelectronic analog-to-digital converter, optoelectronic digital-to-analog converter and applications of the reconfigurable operational amplifier – comparator block.
