(Color online) (a) Scheme of 1D PhC single defect nanocavity with the tapered and outer PhC mirrors on a suspended InGaAsP NB. The 0th-order mode profile in electric-field and its normalized frequency by 3D FEM are also shown. (b) Top- and tilted-view SEM pictures of 1D PhC nanocavity with L = 420 nm, t = 220 nm, r/a = 0.37, w = 570 nm, and Nout = 6 on NB. (c) The L-L curve (left) and single-mode lasing spectrum (right) of the NBL shown in (b). The measured polarization is also shown as the inset.
(Color online) (a) Illustration of transferring the NBLs onto a flexible substrate. The inset image shows how the pump spot and the NB nanocavity look like separately under the optical microscope. (b) The L-L curve and the lasing wavelengths under different pump powers. The designed nanocavity size L of the characterized NBL is 440 nm. (c) The lasing spectra of the NBL before (shorter wavelength) and after (longer wavelength) being transferred onto the flexible substrate.
(Color online) (a) Scheme and picture of the fNBL on the home-made mount surface with bending radius R. The (b) lasing spectra, (c) lasing wavelengths, and linewidths of the fNBL with reduced cavity size L of 390 nm under different R from ∞ to 2.5 mm. (d) Scheme of the radius elongation and rotation of the air hole due to the NB bending in simulations. (e) The FEM simulated wavelength of the fNB nanocavity under different R from 5.0 to 0.0625 mm. The wavelength shows a significant red-shift when R < 1.0 mm. The simulated mode profiles in electric-fields of the fNB nanocavity when R = ∞ and 0.0625 mm are shown as the insets.
