Abstract
A method and apparatus for transmitting and receiving optical signals in a bi-directional transmission system (,) using a common transmission medium (,). Laser radiation at the first wave length and intensity is directed from a laser source (,) to a non-linear optical device (,). The non-linear optical device (,) is responsive to radiation at the first wavelength and intensity is directed from a laser source (,) to non-linear optical device (,). The non-linear optical device (,) is responsive to radiation at the first wavelength and intensity to emit radiation of a second wavelength which is transmitted through the medium (,). The non-linear optical device (,) transmits incident radiation of the second wavelength have less than a selected intensity. A selective mirror (,) is interposed between the source (,) and non-linear optical device,to pass radiation of the first wavelength from the source (,) and directed towards a target (,) radiation of a second wavelength passing from the medium through the non-linear optical device (,) in the opposite direction to radiation from the source (,).
