“…They were chosen for the present experiments because they are well characterized [40], and established in refractive index sensing applications in conventional on-chip configurations [41] [42]. The PhCs were fabricated in a 220 nm thick InGaAsP underetched membrane containing a single layer of self-assembled InAs QDs (density 3 × 10 10 cm −2 ) that emit a spectrum over a broad range from 1400-1600 nm.…”

“…The shift in the x direction (S x ) is 70 nm (0.14a) and in the y direction (S y ) 20 nm (0.04a) (see Figure 1). The cavity modes of this cavity are well known, and have been described before [40]. Before taking the cavity out of the wafer and transferring it to the fiber tip, the cavity modes were determined by measuring the photoluminescence (PL) spectrum.…”

Measuring resonant wavelengths of different modes of a luminescent semiconductor photonic crystal cavity placed on the tip of an optical fiber is proposed and demonstrated for simultaneous measurement of multiple parameters, and is applied to the measurement of temperature and refractive index in the temperature range of 77-370 K. The operation principle is supported by Finite Element Method simulations. The robustness of a simple mounting scheme without adhesives is proven experimentally. The simplicity, extremely small size, and high sensitivity to both refractive index and temperature makes this concept an ideal fiber-optic sensor for a multitude of applications.Index Terms-Optical fiber sensors, Photoluminescence, Photonic Crystals, III-V Semiconductor Materials. 0733-8724 (c)

“…They were used previously in our lab to demonstrate the versatility of spectral encoding. 19 The PhCs have a lattice spacing (a) of 500 nm and a nominal hole diameter of 320 nm (radius-to-lattice-spacing ratio r/a ¼ 0.32). This leads to a calculated photonic bandgap between approximately 1400 and 1700 nm wavelength.…”

“…The H0 cavity has a number of modes (typically four) of which the frequencies can be varied across the bandgap, depending on the parameters of the modified holes. 19 For the present purpose, the choice of the resonant frequencies was somewhat arbitrary, and no optimization of Q-factors was attempted. The diameters of the modified nearest four neighbor holes are 230 nm.…”

The release of photoluminescent InGaAsP photonic crystal nanocavity chiplets from the host chip for creating autonomous functional microparticles is demonstrated. A transfer printing method using a soft polymeric material as a stamp is used to transfer cavity arrays to other substrates. Alternatively, cavities are transferred individually by a nanomanipulation technique. The chiplets can be fully deterministically positioned on both the host chip and another substrate (glass) with the nanomanipulator. The chiplets have the striking property of spontaneously orienting themselves with their plane perpendicular to the receiving surface. At each stage of the process, the condition of the cavities as dependent on their immediate surroundings is monitored from their photoluminescence spectrum. V C 2012 American Institute of Physics.

Multiplexed analysis allows researchers to obtain high-density information with minimal assay time, sample volume and cost. Currently, microcarrier or particle-based approaches for multiplexed analysis involve complicated or expensive encoding and decoding processes. In this paper, a novel optical encoding technique based on nano-silicon dioxide film is presented. Microcarriers composed of thermally grown silicon dioxide (SiO(2)) film and monocrystalline silicon (Si) substrate were fabricated. The nano-silicon dioxide film exhibited unique surface color by low-coherence interference. Hence the colors can be used for encoding at least 100 microcarriers loaded with films of different thickness. We demonstrated that color-encoded microcarriers loaded with antigens could be used for multiplexed immunoassays to detect goat anti-human IgG, goat anti-mouse IgG and goat anti-rabbit IgG, with fluorescent detection as the interrogating approach. This microcarrier-based method also exhibited improved analytical performance compared with a microarray technique. This approach will provide new opportunities for multiplexed target assay development.
