A novel planar waveguide wavelength demultiplexer design for integrated optical triplexer transceiver

A novel wavelength demultiplexer design is proposed for the development of integrated optical triplexer transceiver in fiber-to-the-home (FTTH) applications. Still taking the slab waveguide as the beam confining element along the vertical direction but following a different approach from the arrayed waveguide grating, we use planar lenses to convert the phase front and planar diffraction grating to split the collimated beams in different …
