Cavity refractive indices versus relative channel shift and continuous tuning of the central channel. ( a) The cavity refractive indices, <a onClick="popup('http://www.nanoscalereslett.com/content/7/1/387/mathml/M21','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/7/1/387/mathml/M21">View MathML</a>, versus relative channel position shift normalised to the original channel spacing. (b) Continuous tuning of the central channel for ∆n = −0.026 (red dashed line), ∆n = −0.013 (red dashed dotted line), ∆n = 0 (black line), ∆n = 0.013 (thin blue line) and ∆n = 0.026 (thick blue line).
