Abstract:
1. An optical switch comprising: a birefringent optical channel having a first port and a second port, the birefringent optical channel providing a pair of orthogonally polarized optical pulses at the second port in response to a first optical pulse received at the first port, the orthogonally polarized optical pulses being separated by a delay time; a first coupler having a first port in optical communication with the second port of the birefringent optical channel, a second port adapted to receive a second optical pulse, and a third port; a control optical channel in optical communication with the second port of the first coupler; a nonlinear optical channel having a first port in optical communication with the third port of the first coupler, and having a second port; and a polarization rotation mirror in optical communication with the second port of the nonlinear channel.
