Abstract
We present the first demonstration of E-field tuning of an InP-based g rating-assisted vertical codirectional coupler filter with an InAIGaAs /lnGaAsP MQW region in one of the waveguide cores. This filter exhibit s 16 nm tuning by QW-electrorefraction, which is the highest value rep orted to our knowledge. The device has 3.2 nm bandwidth at 1568 nm for 1.6 mm interaction length, very low losses, good sidelobe suppression , high coupling efficiency and a modified polarization dependence.
