Abstract:
A laser system, comprising:a broadband laser generating optical output signals including a plurality of predetermined wavelength components,a bi-directional optical switch having a first port and a plurality, N, of second ports, said bi-directional optical switch establishing an optical coupling between said first port and a selected one of said plurality of second ports;a circulator having a first port coupled to said broadband laser, a second port coupled to said first port of said bi-directional optical switch and a third port for providing output optical signals;a plurality of wavelength selective reflectors, each being coupled to a corresponding one of said optical switch second ports, and each reflecting optical signals at a predetermined one optical wavelength selected from a plurality of predetermined optical wavelengths; andan apparatus for generating control signals;whereby said control signals operate said bi-directional optical switch to select a wavelength selective reflector such that said optical output signals are coupled to said selected wavelength selective reflector to produce optical signals at a selected wavelength at said circulator third port.
