Abstract :
An investigation of optimal waveguide layout shapes for vertically-coupled, wafer-bonded InP/InGaAsP optical add-drop multiplexers has been performed through integration of the coupled-mode Ricatti equation, providing potential sidelobe levels of less than -32 dB and filter bandwidths over 20% narrower than those of previous devices. Effects of nonideal processing conditions on filter performance are analyzed as well.
