Abstract: PURPOSE: A logic element using saturable absorbers is provided to apply the same current to the first saturable absorber and the second saturable absorber, without a change of a path phase difference caused by optical strength of an input signal, thereby alleviating restrictions on an operational input optical strength range. CONSTITUTION: The first saturable absorber(117) inputs power in which the first input signal is synthesized with a reference signal, has a more passing power than an absorbing power if the power is more than the first transparent input optical strength, and has a more absorbing power if the power is less than the optical strength. The second saturable absorber(118) inputs power in which the first input signal, the second input signal, and the reference signal are synthesized together, has a more passing power if the power is more than the second transparent input optical strength, and has a more absorbing power if the power is less than the optical strength. Combiners(114a,114b) combine an output of the first saturable absorber(117) with an output of the second saturable absorber(118).
