Abstract

IN UN FILTRO OTTICO INTEGRATO A CAVITA' RISONANTE, LA CAVITA' RISONANTE (2) E' OTTENUTA MEDIANTE TRATTI DI GUIDA OTTICA (5a...5c, 6a...6c, 7, 8) CHE COSTITUISCONO DUE ACCOPPIATORI A Y AFFACCIATI E UNITI IN CORRISPONDENZA DELLE ESTREMITA' DEI BRACCI (5a, 5b, 7, 6a, 6b, 8) DELLE Y. I BRACCI DELLE Y (5a, 5b, 7, 6a, 6b, 8) SONO TRATTI DI GUIDA MONOMODALI E I GAMBI DELLE Y (5c, 6c) SONO TRATTI DI GUIDA BIMODALI, RESI SPECULARI ALL'ESTREMITA' LIBERA (9, 10), E HANNO LUNGHEZZA TALE CHE UNA RADIAZIONE DA SELEZIONARE ENTRANTE IN UNO DEI TRATTI BIMODALI (5c; 6c) PROVENENDO DA UNO DEI TRATTI MONOMODALI (5a; 6b) PASSA DALLO STESSO TRATTO BIMODALE, DOPO RIFLESSIONE ALL'ESTREMITA', ALL'ALTRO TRATTO MONOMODALE (5b; 5a) DELLA CAVITA' (2).
