Dynamically Controllable Photonic Crystals

DYNAMICALLY CONTROLLABLE PHOTONIC CRYSTALS

Tech for Transfer

PatentSale

08-10-2014

The Invention Dynamically Controllable Photonic Crystals (PhCs) allow for dynamic control of electromagnetic (EM) wave motion through a silicon PhC comprising of arrays of micro-cavities. This is achieved by changing the local refractive index in the vicinity of a micro-cavity. This enables the dynamic manipulation of the light, similar to the manipulation of electrical carriers in semiconductors.

Photonic crystal solar cell

PHOTONIC CRYSTAL SOLAR CELL

Tech for Transfer

TTO

17-12-2015

This invention presents a photovoltaic cell contained within a photonic crystal structure. It incorporates both photovoltaic and photonic structures into a single unit. The photonic crystal guides and concentrates sunlight into a photonic optical cavity, which is composed of photovoltaic material comprising a semiconductor heterojunction for forming a photovoltaic current. The solar cell is self-focusing in that it utilizes the known property of photonic crystals to propagate light in any direction, provided that the light is within a transmissible band. This property is exploited here to also make the device more efficient by concentrating incoming light into the photovoltaic region.

Photonic crystal lasers for chemical detection

PHOTONIC CRYSTAL LASERS FOR CHEMICAL DETECTION

Tech for Transfer

TTO

17-12-2015

The invention provides the ability to utilize photonic crystal lasers to detect a chemical in an analyte. It utilizes a laser with an open cavity and a photonic crystal lattice structure that defines a suitable geometry for such a cavity. The analyte is introduced directly into a high optical field of the cavity. The cavity is pumped and an emission from the laser is used to detect the presence of the chemical in the analyte. The unique design of the laser cavity geometry (i.e., comprising photonic crystal) in combination with the ability to place the analyte directly into the cavity provides the capability to conduct high-resolution spectroscopy with single-molecule sensitivity. The nanocavity lasers of the invention may be used to perform spectroscopic tests on femtolitre volumes of analyte.
