“…The initial placement of the photonic crystal membrane without tilt is such that the nanostructure lines of the sensor membrane have an angle of 45° to both polarization filters. Thus, only light interacting with the photonic crystal can be seen on the photos that were taken by the microscope as shown in [14]. An image of the sample is photographed with a camera and part of the transmitted light is guided to a spectrometer.…”

“…Figure 1(b) schematically shows the scattering for two different angles. When the photonic crystal slab is illuminated and observed through crossed polarization filters, light not interacting with the grating structure is filtered out and only the GMRs of the photonic crystal are observed resulting in a distinct color impression on a camera [14].…”

Abstract:We demonstrate a pressure sensor based on deformation of a periodically nanostructured Bragg grating waveguide on a flexible 50 µm polydimethylsiloxane membrane and remote optical read out. A pressure change causes deformation of this 2 mm diameter photonic crystal membrane sealing a reference volume. The resulting shift of the guided mode resonances is observed by a remote camera as localized color change. Crossed polarization filters are employed for enhancing the visibility of the guided mode resonances. Pressure values are calculated from the intensity change in the green color channel using a calibration curve in the range of 2000 Pa to 4000 Pa. A limit of detection (LOD) of 160 Pa is estimated. This LOD combined with the small size of the sensor and its biocompatibility render it promising for application as an implantable intraocular pressure sensor.

“…In this transmission experiment the light source is a halogen lamp providing white light. To filter background light, which is not interacting with the PCS, we use crossed polarization filters before and after the PCS [17]. GMRs are collected with a microscope objective (20x) and are directed to a spectrometer.…”

For label-free assays employing photonic crystal slabs (PCSs), the sensitivity is one of the most important properties influencing the detection limit. We investigate the bulk sensitivity and the surface sensitivity of 24 different PCSs fabricated by injection molding of PMMA and subsequent sputtering of a Ta 2 O 5 high-index layer. The duty cycle of the linear grating is varied in steps of 0.1 between 0.2 and 0.7. Four different Ta 2 O 5 layer thicknesses (89 nm, 99 nm, 189 nm, 301 nm) are deposited. Both bulk and surface sensitivity are optimal for a Ta 2 O 5 layer thickness of 99 nm. The maximum bulk sensitivity of 138 nm/RIU is achieved for a duty cycle of 0.7, while the maximum surface sensitivity of 47 nm/RIU is obtained for a duty cycle of 0.5. Good agreement between experimental results and finite-difference time-domain (FDTD) simulations is observed. The PCSs sensitivity is linked to the mode intensity distribution.

“…In crosspolarization measurement mode, 23,24 the nonresonant path through the photonic crystal membrane contributing to the Fabry-Perot background in the transmission spectrum 1 is suppressed, while the resonant transmission at the resonance frequency is readily detected. As a result, guided resonance modes appear as peaks in the transmission spectrum.…”

The authors report the fabrication and optical characterization of fully suspended, transferrable, and deflectable silicon photonic crystal nanomembranes. Starting with a silicon-on-insulator wafer, the authors used electron beam lithography and inductively coupled plasma reactive ion etching (ICP-RIE) to introduce various photonic crystal patterns in silicon. A membrane containing the photonic crystal patterns was then defined by photolithography combined with ICP-RIE and released from the handle wafer by wet chemical etching. Finally, a free-standing photonic crystal membrane was obtained by a wet transfer and alignment process over a perforated foreign substrate. In the fabricated structures, the authors observed vivid structural colors in dark-field optical images of square lattice photonic crystals and measured a guided resonance mode with a quality factor as high as 5600 in a novel slot-graphite photonic crystal.
