چکیده
|
We investigated angle-resolved tuning performance of the double resonance modes of waveguide metallic grating structures, where the incident angle was changed in the plane formed by the extending direction of the grating lines and the wave vector with the grating plane tilted with respect to the vertical axis. double resonance modes were observed due to tilting of the grating, which were tuned simultaneously to the blue with increasing the angle of incidence. the spectral separation between the resonance modes can be adjusted simply by changing the tilting angle of the grating. such a double resonance device is important for exploring multichannel optical filters, optical switching device, or sensors.
