“…Wavelength-scale photonic crystals (PhC) have emerged as key elements for many applications ranging from cavity quantum electrodynamics [1,2], low threshold lasers [3,4], nonlinear optics [5][6][7], high performance filters [8][9][10][11], beam-splitters [12][13][14] and optical switches [15,16]. In the past decade, there has been a considerable research effort to develop photonic crystal microcavities characterized by high Q-factor and small mode volume comparable to (λ/n) 3 .…”
