Figure 3
From: Transmission comb of a distributed Bragg reflector with two surface dielectric gratings
Transmission spectra of the (a) TE wave and (b) TM wave for several grating periods. For easy observation, the lines are offset in steps of 1. The dashed arrows in (a,b) show the shift direction for increasing grating period (
nm, fg = 0.5 and 
).
