Abstract
A method of wavelength conversion includes receiving a modulated optical signal of a first wavelength and using the modulated optical signal to optically pump an active medium to generate and transmit a like modulated optical signal of a second wavelength, all of which is affected entirely within an optical domain without electrical contacts. Also, an optical wavelength converter includes an active medium that is optically pumped by a modulated optical signal of a first wavelength and transmits the modulated optical signal at a second wavelength. The active medium may be contained in a detachable, external module for wavelength conversion of a fixed wavelength source.
