  We demonstrate the existence of tunable bound-states in continuum (BIC) in a
1-dimensional quantum wire with two impurities induced by an intense
monochromatic radiation field. We found that there is a new type of BIC due to
the Fano interference between two optical transition channels, in addition to
the ordinary BIC due to a geometrical interference between electron wave
functions emitted by impurities. In both cases the BIC can be achieved by
tuning the frequency of the radiation field.
