Semiconductor Laser Source with Electrically Tunable Emission Wavelength

A tunable semiconductor with novel wavelength adjusting technology Background: An adjustable semiconductor light source, such as lasers or light diodes, have a high demand for variable wavelengths in a controllable manner. Although there are methods to change the wavelength of a light beam, they are either impractical or uncontrollable. There is a...

Bolometric Sensor with High TCR and Low Resistivity

The invention provides a novel way of operating bolometers in the resistive hysteresis region of a phase-transitioning VO2 film. Background: Visualization of infrared (IR) radiation is achieved by projecting an IR picture onto a sufficiently large 2D matrix of small microbolometers. Using electrical signals, outputs can be visually displayed, thus...

Large-Area PIN Diode with Reduced Capacitance

Novel design of PIN diode that simultaneously has a low capacitance and a large area of effective collection of photo-generated charge Background: It is highly desirable to implement a PIN diode that collects light from the same area but has a substantially lower capacitance, so that the sensitivity threshold can be greatly improved. The diode capacitance...

Sensors for Power Distribution Network

Monitoring the state of a power distribution network so that control rooms can be alerted to changes before the point of complete shut down Background: A significant shortcoming to power grid distribution systems is the lack of status. Systems do not know their own state nor the quality of their state. This is understood in times of failure such as...
