(Color online) (a) SEM images of the fabricated L3 cavities. (b) Experimental setup. Inset: near field emission (dashed line indicates the cavity position). Experimental (c) and simulated (d) far field images. White line: light line. Dashed line: maximum angle collected. Parameters of the FDTD simulations are: a = 435 nm, r/a = 0.3, n = 3.3, shift of the two end holes = 0.15a, and membrane thickness = 265 nm.
(Color online) Near field emission (a), (f) and photoluminescence spectrum (b), (e) of two L3 cavities separated by 3 rows of holes. Experimental (c), (g) and simulated (d), (h) far field patterns. (a)-(d) Symmetric (λ <) mode (pump power = 100 μW). (e)-(h) Antisymmetric (λ >) mode (pump power = 47 μW). In (a), (f): dashed lines indicate the cavity position. Simulated splitting: λA − λS ≈ 4 nm.
(Color online) Idem as in Fig. 2 for two L3 cavities separated by 5rows of holes and pump power = 140 μW. Simulated splitting: λA − λS ≈0.7 nm.
