Question

2. Array waveguide grating (AWG) Lo+(m-1)AL The refractive index of the waveguide is Nc-1.459, and the refractive index of the slab is ns-1.462. D-250?m, and d- 50um. The wavelength ?-1.5?m. What's the length increment ?L lf we want the AWG has the resolution of 1nm. f- 1cm Lo

Answer 1

Given dhed, Ne = 1,462 d So um find Aa increment AL d= Sox 10-6 maters Ne = 1.462

9 Thae tore AL - 9,42x 1618
