We investigate the temperature sensitivity of silicon-based optofluidic photonic crystal double-heterostructure resonators. We systematically study the optical properties of these resonators as function of temperature, specifically demonstrating the potential for creating temperature-insensitive photonic crystal devices.
We demonstrate an expanded k-space evanescent coupling technique for characterizing the dispersion and loss of photonic crystal waveguides (PCWG) by measuring the Fabry-Perot spectrum of a closed waveguide using a highly curved taper.
We demonstrate spectral and spatial reconfigurability of silicon photonic crystal cavities by microfluidic infiltration of selected air-holes. High Q-factors for a broad range of cavity lengths are shown, highlighting the flexibility of our approach.
We demonstrate post-processed, reconfigurable microfluidic double-heterostructure cavities in silicon-based photonic crystal slab waveguides, formed by selective micropipette fluid infiltration. An examination of the induced cavities, performed by evanescent coupling, is presented.
We demonstrate reconfigurable microfluidic photonic crystal double-heterostructure cavities by local fluid infiltration of select air holes. Properties of the microfluidic cavities are experimentally studied by evanescent coupling and analyzed by numerical simulations.
We demonstrate post-processed and reconfigurable photonic crystal double-heterostructures via selective fluid infiltration. Quality factors of Q = 4,300 are obtained from initial measurements. The presented defect-writing technique does not require nanometer-scale alterations in lattice geometry and may be undertaken at any time after device fabrication.
We present experimental results on photosensitive post-tuning the dispersion of a two-dimensional photonic crystal waveguide made from chalcogenide glass. A 5 nm shift of the resonant wavelength is reported.
We demonstrate the capability to post-tune a photonic crystal nanocavity resonance without affecting its quality factor via the presence of an evanescently coupling tapered optical fibre. A 3 nm shift is reported.
