Novel 1.3/1.55 /spl mu/m dual-wavelength receiver having embedded fiber circuit for optical subscriber systems

Summary form only given. We propose and demonstrate a novel dual-wavelength receiver, which has an embedded fiber circuit that demultiplexes 1.3- and 1.55-/spl mu/m signals to separate photodiodes mounted on a single-substrate surface. The circuit contains wavelength separation filters placed in slits fabricated in the fiber path by a conventional cutting saw. Low-circuit loss and high-receiver performance is realized for both WDM signals.
