Abstract

We present a new electro-optic (EO) tunable bandpass filter design based on a long-period-grating-assisted asymmetric waveguide coupling mechanism. A narrow passband width of <0.2 nm and a large wavelength tuning range exceeding 30 nm can be obtained at a low driving voltage of ~16 V. This type of EO tunable filter would form key building blocks in dynamic wavelength division multiplexing (WDM) optical networks.
