Photonic 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 کاملAll-polymer photonic crystal slab sensor.
An all-polymer photonic crystal slab sensor is presented, and shown to exhibit narrow resonant reflection with a FWHM of less than 1 nm and a sensitivity of 31 nm/RIU when sensing media with refractive indices around that of water. This results in a detection limit of 4.5 × 10(-6) RIU when measured in conjunction with a spectrometer of 12 pm/pixel resolution. The device is a two-layer structure...

متن کاملSurface waves and volume waves in a photonic crystal slab.
The volume and surface waves supported by a 2D PC slab with termination condition are systematically studied using the rigorous modematching method incorporating the Floquet's solutions. It is interesting to observe that the surface waves are caused by the perturbation of the PC-slab modes from the imposed termination condition, enabling the transition from volume wave to surface wave. The pert...
متن کاملDMSO-based photonic crystal fiber sensor with enhanced sensitivity
We construct a dimethylsulfoxide (DMSO)-based photonic crystal fiber (PCF) temperature sensor with enhanced sensitivity. A solid-core PCF with large mode area is employed to supply the in-line Mach– Zehnder interference between the fundamental and cladding modes. Thus, temperature sensing can be realized because of the shift of interference spectrum at different temperatures.The DMSO solvent is...
