but they say theye made a breakthrough that could take thermophotovoltaics far beyond where it gone before. mit thermophotovoltaics MIT nanophotonic solar thermophotovoltaic device, with an array of multialled carbon nanotubes as the absorber, a oneimensional silicon/silicon dioxide photonic crystal as the emitter
T) he team inserted a two-layer absorber-emitter device made of novel materials including carbon nanotubes and photonic crystals between the sunlight and the PV cell.
This layer is bonded tightly to a layer of a photonic crystal, which is engineered precisely so that when it is heated by the attached layer of nanotubes,
photonic crystal fibre (PCF) lasers offer better and more accurate beam quality, are highly efficient, use less power,
and reversing the effects of loss in various other physical systems such as in photonic crystal activities plasmonic structures and metamaterials.
and in the ultra-small cavities of photonic crystals#components of chip-based lasers and light-emitting diodes."
The material is a two-dimensional metallic dielectric photonic crystal and has the additional benefits of absorbing sunlight from a wide range of angles

On each side of the seesaw benches researchers etched an array of holes called photonic crystal cavities.
A photonic crystal fiber was used to generate (quasi-white light) supercontinuum to probe the spectral response of select regions within the array.
In this case, the exceptional rings were found in a slab of nanostructured material called a photonic crystal.
#New Nanosheet-Based Photonic crystal Changes Color in Response to Moisture LMU chemists have developed a photonic crystal from ultrathin nanosheets
Unparalleled sensitivity and response time Photonic crystals are arranged periodically nanostructures which have the ability to reflect, guide and confine light.
Lotsch and her team have developed now photonic crystals based on nanosheets of phosphatoantimonic acid. The new nanomaterial is extremely moisture sensitive and at the same time chemically stable,
The material reacts to the humidity change within a few milliseconds This is a property that is fundamentally well known and characteristic of so-called photonic crystals.
In response to this problem the engineers developed a visibly transparent overlay more technically a silica photonic crystal overlay that increases solar cell efficiency by radiating the heat of cells away from them much like how we naturally radiate heat from our bodies to prevent overheating.

They then used electrohydrodynamic jet (e-jet) printing technology to precisely print the QD-embedded polymers onto photonic crystal structures.
These photonic crystals limit the direction that the QD-generated light is emitted meaning they produce polarized light,

#Photonic crystal fibre: a multipurpose sensor Glass fibres can do more than transport data. A special type of glass fibre can also be used as a high-precision multipurpose sensor,
as researchers at the Max Planck Institute for the Science of Light (MPL) in Erlangen have demonstrated now("Flying particle sensors in hollow-core photonic crystal fibre").
which can literally sense different physical quantities such as electric field, temperature or vibrations through the inside of this hollow-core photonic crystal fibre.
which flies through the hollow channel in the interior of a photonic crystal fibre to measure different physical quantities, for example the electric field along the optical fibre.
Two laser beams manoeuvre a microbead through a hollow glass fibre In photonic crystal fibres (PCFS), which were invented around 20 years ago by Philip Russell, Director at the Max Planck Institute for the Science of Light,
The special properties of photonic crystal fibre, however, enable several applications that are not possible with conventional optical fibres.
whether hollow-core photonic crystal fibres are suitable as sensors by initially using the fibres to measure electric fields, vibrations and temperatures.
