摘要： An oscillation device has a resonant tunneling diode formed by interposing a gain medium including a first barrier layer, a quantum well layer and a second barrier layer between a first thickness adjusting layer and a second thickness adjusting layer. The oscillation device also has a switch for switching the polarity of a bias voltage being applied to the resonant tunneling diode. The first thickness adjusting layer and the second thickness adjusting layer have different thicknesses. Thus, a single oscillation device is driven to oscillate with different oscillation frequencies.

摘要： Provided are an image forming apparatus and an image forming method which are capable of obtaining an image of a measured object using a relatively simple structure in a short time. In the image forming apparatus, an electromagnetic wave generated by an electromagnetic wave generator is emitted to the measured object through a spatial modulation unit for spatially modulating a signal intensity. An electromagnetic wave that has passed through the measured object is measured by an electromagnetic wave detecting unit. A measurement signal is processed by a signal processing section based on a reference signal synchronized with the signal intensity modulated by the spatial modulation unit. The image is formed by an image acquisition section.

The multiple quantum well includes at least two regions A and a region B disposed therebetween. The region A includes a plurality of energy levels, and a carrier is transported from a specific energy level i to a specific energy level f in the region A through one of the potential barriers by photon-assisted tunneling. The region B includes a plurality of energy levels, and an energy relaxation is performed with a relaxation time shorter than a transit time of the carrier in the region A from a specific energy level e to a specific energy level g in the region B. When an electric field is applied, electric current flows through the multiple quantum well and light is emitted or absorbed in the region A.
