Abstract

1290649 Optical band injection filter WESTERN ELECTRIC CO Inc 5 Aug 1969 [7 Aug 1968] 6467/72 Divided out of 1288953 Heading G2J [Also in Division H1] A band injection filter comprises a length of transmission line and at least one tuned "resonant cavity", formed by a closed transmission line supportive of travelling waves, said line being in coupling relationship with said cavity of two locations for inducing a pair of equal oppositelypropagating levelling waves in said cavity. On disclosed the "cavity" is a material of a higher refractive index than the substrate carrying it.
