Abstract :
We investigate the spectral and angular response of a passive tilted-grating structure (TGS) in the frame of a first-order coupled-wave formalism. Its resonance modes can be understood as resulting from a competition between those of the main Fabry-Perot (FP) resonator and those of the tilted grating. Due to the structural non-reciprocity provided by the latter, resonance modes of the whole cavity appear highly sensitive to the internal angle
