ABSTRACT
Thus, the output circulated light field, E0, for the right nanoring is given by
(5.14)
Similarly, the output circulated light field, E0L, for the left nanoring at the left side of the add/drop system is given by
(5.15)
where k3 is the intensity coupling coefficient, g 3 is the fractional coupler intensity loss, a is the attenuation coefficient, kn = 2p/l is the wave propagation number, l is the input wavelength light field and L2 = 2pRL, RL is the radius of left nanoring. From Eqs (5.3)–(5.15), the circulated light fields, E1, E3 and E4 are defined by given x1 = (1 – g 1)1/2, x2 = (1 – g 2)1/2, y1 = (1 – k 1)1/2, and y2 = (1 – k 2)1/2.
