Cell imaging using GaInAsP semiconductor photoluminescence.
We demonstrate label-free imaging of living cells using a GaInAsP semiconductor imaging plate. The photoluminescence (PL) intensity is changed by immersing the semiconductor wafer in different pH solutions and by depositing charged polyelectrolytes on the wafer. Various observations indicate that this phenomenon arises from the radiative and surface recombination rates modified by the Schottky ...
متن کاملSensitivity enhancement in photonic crystal slab biosensors.
Refractive index sensitivity of guided resonances in photonic crystal slabs is analyzed. We show that modal properties of guided resonances strongly affect spectral sensitivity and quality factors, resulting in substantial enhancement of refractive index sensitivity. A three-fold spectral sensitivity enhancement is demonstrated for suspended slab designs, in contrast to designs with a slab rest...
متن کاملPhotonic crystal slab sensor with enhanced surface area.
In this work, we demonstrate improved molecular detection sensitivity for silicon slab photonic crystal cavities by introducing multiple-hole defects (MHDs), which increase the surface area available for label-free detection without degrading the quality factor. Compared to photonic crystals with L3 defects, adding MHDs into photonic crystal cavities enabled a 44% increase in detection sensitiv...
متن کاملEnhanced photoluminescence emission from two-dimensional silicon photonic crystal nanocavities
We present a temperature-dependent photoluminescence study of silicon optical nanocavities formed by introducing point defects into twodimensional photonic crystals. In addition to the prominent TO-phonon-assisted transition from crystalline silicon at ∼1.10 eV, we observe a broad defect band luminescence from ∼1.05 to ∼1.09 eV. Spatially resolved spectroscopy demonstrates that this defect band...
متن کاملDiamond photonic crystal slab: Leaky modes and modified photoluminescence emission of surface-deposited quantum dots
Detailed analysis of a band diagram of a photonic crystal (PhC) slab prepared on a nano-diamond layer is presented. Even though the PhC is structurally imperfect, the existence of leaky modes, determined both theoretically and experimentally in the broad spectral region, implies that an efficient light interaction with a material periodicity occurs in the sample. It is shown that the luminescen...
