Inventor: CAPASSO FEDERICO
IPC: H01S5/0625
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To make it possible to modulate a laser in an electric field in an IR intermediate wavelength range by a method wherein an active region is provided with a plurality of repetition units consisting of a plurality of layers, the laser oscillation transition of the laser is turned into the non-resonance tunneling transition of charge carries from a first quantum state to a second quantum state and the frequency of photons is set as the function of an electric bias. SOLUTION: In an article, which comprises a laser having first and second contacts to apply an electric bias to a semiconductor structure comprising an active region 12, the region 12 has a plurality of the same repetition units consisting of a plurality of layers in the directions intersecting orthogonal the contacts and is selected so that a laser oscillation transition of the laser is a non-resonance tunneling transition of charge carriers from a first quantum state to a second quantum state. This transition is achieved by radiation of photons of an hν of energy. Here, the (h) is the constant of a plank and the (ν) is the frequency of the photons. This frequency of the photons is the function of the electric bias, which is applied to the semiconductor structure, and the laser can be modulated in an electric field in an IR intermediate wavelength range.

Abstract: PURPOSE:To enable radar equipment to change its transmitting frequency at a high speed without losing its moving target detecting function by forming transmitting signals having different frequencies by combining two kinds of local signals which are coherent sine wave signals. CONSTITUTION:Two kinds of local signals generated from local transmitters 23 and 21 are supplied to a two-frequency forming device 27. The device 27 generates sum- and difference-component transmitting signals from input signals and finally generates transmitting RF signals by synthesizing the transmitting signals The transmitting RF signals are radiated from a transmission-reception antenna 12 as transmitting waves after the signals are made into pulses. The reflected waves of the transmitting waves from a fixed or moving target are received by means of the antenna 12 and supplied to a two-signal frequency converter 36 after they are subjected to low-noise amplification 31. The converter 36 extracts sum- and difference-component received signals corresponding to the two kinds of transmitting signals, converts the frequency of the signals by mixing the signals with each other by making their timing coincident with each other, and detects a frequency-deviated component. Then a moving target display device 4 displays the moving target.
