Wavelength-scale, high Q-factor photonic crystal cavities [1, 2] have emerged as a platform of choice for on-chip manipulation of optical signals, with applications ranging from low-power optical signal processing [3] and cavity quantum electrodynamics [4, 5] to biochemical sensing. Many of these applications, however, are limited by the fabrication tolerances and the inability to precisely con...

We investigate the design, fabrication and experimental characterization of high Quality factor photonic crystal nanobeam cavities in silicon. Using a five-hole tapered 1D photonic crystal mirror and precise control of the cavity length, we designed cavities with theoretical Quality factors as high as 1.4 × 10. By detecting the cross-polarized resonantly scattered light from a normally incident...

The novelty of this study is presentation of an exact solution for prediction of postbuckling behavior of shear deformable micro- and nano-scale beams based on modified couple stress theory and using principle of minimum potential energy. Timoshenko and Reddy-Levinson beam theories are applied to consider the shear deformation effect and Von Karman nonlinear kinematics is used to describe the n...
