Tunable wavelength filters using λ/4‐shifted waveguide grating resonators

We report on wide tuning range 1.5 μm wavelength filters using λ/4‐shifted waveguide grating resonators. A tuning range of a transmission resonance wavelength as wide as 42 A by carrier injection and two‐channel wavelength signal switching was achieved.
