Abstract:
1. A system for generating a millimeter wave signal ( 100 ) comprising: a Brillouin-Erbium fiber laser ( a source laser ( an optical directional coupler ( an Erbium doped fiber amplifier ( a four port circulator ( a Brillouin gain medium ( a fourth port of said circulator connected to a second input of said optical directional coupler wherein said optical directional coupler receives said signal from said fourth port of said circulator and outputs a portion of said signal to a first output and a second portion to a second output of said optical directional coupler; and a first isolator having a first end connected to said second output of said optical directional coupler, said first isolator having a second end connected to a first end of a first fiber Bragg grating, wherein said fiber Bragg grating reflects second-order and fourth-order Stokes signals, and wherein said reflected Stokes signals are absorbed by said first isolator.
