Abstract :
Summary form only given. We present detailed modeling and experimental results for an improved design of an InGaAsP/InP wavelength demultiplexer based on a monolithically-integrated Rowland circle waveguide grating fabricated using chemically-assisted ion beam etching. The design incorporates ten wavelength channels at 1.55 /spl mu/m with a uniform spacing of 2 nm and multimode output waveguides to flatten channel response and reduce sensitivity to polarization.
