Abstract
A demultiplexing apparatus is disclosed which comprises a pulse generator (4), a phase control device (3), and an optical switching device (1), e.g., a NOLM. The phase control device (3) controls the pulse generator (4), whose pulse initiates switching operations in the optical switching device (1) depending on the magnitude of an electric signal derived from the output (8) of the optical switching device (1). The phase control device (3) includes a noise source (26) which disturbs the pulse in a defined manner.
