PHOTONIC AWG WITH WIDER BANDWIDTHS AND LONGER TIME APERTURESTech for Transfer TTO 17-12-2015 Optical arbitrary waveform generation (OAWG) is a technique where a photonic device is programmed to create the desired output as an optical waveform with an arbitrary modulation format which is specified by the user. Purely electronic AWG is limited in bandwidth while current optical AWG systems suffer from other limitations. This invention provides a new device and method for OAWG capable of using wider bandwidths and extended time apertures. It involves generating a frequency-shifted replica of a first narrowband waveform and a second narrowband waveform, and then combining them to generate a broadband waveform.

LOW-COST, HIGH-QUALITY SINGLE-LAYER PHOTONIC CRYSTAL STRUCTURETech for Transfer TTO 17-12-2015 This invention provides a new method of forming a single-layer photonic crystal structure. It includes a depositing electrophoretic suspension and two separated electrodes formed at the upper and lower parts of a container. An electric voltage is applied to the electrodes to form an electric field, such that particles in the electrophoretic suspension will form a single-layer photonic crystal structure on one of the electrodes by an electrophoresis self-assembly technique. The single-layer photonic crystal structure has a low cost, good quality and recurring property. Photonic Crystals Thin-Film Materials Tell me more |

PHOTONIC CRYSTAL LASERS FOR CHEMICAL DETECTIONTech 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. Lasers Photonic Crystals Tell me more |

PHOTONIC CRYSTAL PRESSURE SENSORTech for Transfer TTO 18-12-2015 The present invention provides a microscale pressure sensor that exhibits high sensitivity in a small form factor. The sensor is a bridged device in which a photonic crystal waveguide, surrounded by a photonic crystal slab, is suspended over a dielectric substrate. Under applied pressure, the photonic crystal waveguide is deflected toward the substrate, causing a decrease in optical transmission across the waveguide due to the coupling of the evanescent field of the guided mode to the dielectric substrate. The waveguide can be coupled to a photonic crystal microcavity, which increases evanescent coupling. This inventive design enables a higher sensitivity and better tolerance to manufacturing imperfections. Photonic Crystals Waveguides Tell me more |

BISTABLE PHOTONIC CRYSTAL WITHOUT EXTERNAL POWER CONSUMPTIONTech for Transfer TTO 18-12-2015 The present invention provides the way to create a photonic crystal with fast response time and wide tunable range of wavelength, and meanwhile, remain at a stable state without external power consumption. The photonic crystal has a plurality of voids and each surface of void has an hydrophobic film. When the photonic crystal is immersed in a predetermined liquid, the crystal has two stable states. The first stable state is to fill the plurality of voids with the predetermined liquid, and the second stable state is to exclude the liquid from the plurality of voids. Owing to the energy barrier between the first and second stable states, the photonic crystal can remain at either of the two states without external power consumption.
