Abstract
An optical oscillatorcombines optical signals L' and Lto generate an optical signal L. The optical signal L′ includes light waves W′ and W′ having frequencies spaced apart by a frequency difference Δf. The optical signal Lincludes light waves Wand Whaving frequencies spaced apart by a frequency difference Δf. The optical oscillatorseparates the optical signal Linto optical signals Land L, wherein the optical signal Lincludes the light waves W′ and Wand the optical signal Lincludes the light waves W′ and W. The optical oscillatorcompares the frequency differences Δfand Δfbased on frequency difference Δfbetween the light waves W′ and Wincluded in the optical signal Land frequency difference Δfbetween the light waves W′ and Wincluded in the optical signal L
