Consider a waveguide grating multiplexer that has the values for the operational variables listed in Table 10.12.
(a) Find the waveguide length difference.
(b) Calculate the channel spacing Av and the corresponding pass wavelength differential A X.
(c) What is the free spectral range for diagonally opposite ports in this device
(d ) Letting Q₁= jx/Lf and 0 o = kx/L f , what is the FSR for j = 2 and k = 8
