We propose and theoretically investigate a novel one-dimensional photonic crystal nanocylinder cavity (PCNC) that can support the second-order transverse-electric-like (TE2) mode. Three-dimensional finite-difference time-domain simulations show that the TE2 mode of the PCNC possesses an ultrahigh quality factor of 1.22 × 108 and a small mode volume of when the PCNC is made of high-index material of silicon. For the PCNCs which are made of low-index materials, the corresponding quality factors of TE2 modes reach the highest values relative to previously demonstrated PhC nanobeam cavities with the same low-index materials to the best of our knowledge. We believe the PCNC will be a highly promising candidate for low-threshold high-speed nanoscale lasers and cavity optomechanics.
